SOURCE: whenever i enter coordinates for

Two possibilities:

  1. Graph is out of range (out of the window). If your data is positive set Xmin=0 and Ymin=0. Set Xmax a bit larger than the maximum x-value and YMAX a bit larger than the maximum y-value. You can also press [ZOOM] and select [9:ZoomStat].
  2. To mark the points you may have select the dot and your calculator screen is too dim.
To help you setup your calculator To perform regression analysis I am inserting here a copy of a more detailed post of mine where I show the complete procedure applied to a quadratic regression.

Before doing statistics, you have to prepare the calculator by clearing old data that may generate errors.

A. TO CLEAR OLD DATA
  1. Press [2nd][ ] (MEM) to open the memory management screen.
  2. Press [4:ClrAllLists]
  3. The command echoes on main screen, press [ENTER] to run it.
  4. Calculator displays Done.
B. RUN the SETUP EDITOR Command
  1. Press [STAT][5:SetUpEditor] [ENTER] ; calculator displays Done.
C. TURN DIAGNOSTICSON option (optional)

To obtain the correlation coefficient in a statistical analysis on the TI8xPlus family of calculators you must activate the DIAGNOSTICSON option. To access the command
  1. You press [2nd] [0] (CATALOG)
  2. While the list of commands is displayed, press [X^-1] (D)
  3. Cursor jumps to first command that starts with D, dayOfWk(
  4. Press the DownArrow 9 times to reach DIAGNOSTICSON
  5. Select it and press [ENTER]
  6. Command echoes on main calculator screen with blinking cursor
  7. Press [ENTER] to set the option
  8. Calculator displays Done.
From now on, if a correlation coefficient has meaning for a regression model, it will be calculated along with the other statistical results. If it has no meaning to the model it will not be calculated.

D. ENTER THE DATA
Press [STAT][1:Edit]
Type in your D (X ) values in L1 and the N (Y) values in L2 (see picture 1). Sorry the picture does not have YOUR values.
894afd6.jpg

TO OBTAIN statistical RESULTS (optional)
  1. After you finish entering the data, press [2nd][Quit] to exit StatEditor.
  2. Press [STAT] and highlight Menu (CALC)
  3. In the list select [2:2-Var Stats]
  4. Command echoes on main screen.
  5. Press [ENTER] to calculate the stats
Here is what one gets with the data above.

f2d3743.jpg
Notice the Down Arrow next to n=7. That means the results screen has more values. Press the Down Arrow to display.
ab847d7.jpg
You notice that the n=7 line now has an arrow pointing Up. Notice the Down Arrow on the bottom line (more data is coming). Here is the rest of the statistical results.
37fb2ba.jpg
There is no arrow at the bottom of the picture. End of statistical results.
The screen captures with 2-Var Stats summarize all the statistics.

However there is no correlation coefficient, no line of best fit, etc. To obtain that you have To perform a regression analysis.

E. PERFORM A REGRESSION ANALYSIS
To perform a regression analysis, you must try several regression models and then find the one that mimics the raw data best. Select Regression model ( exponential, linear, sine, quadratic, etc.) Here I selected Exponential
  1. Press [STAT] , highlight [CALC]
  2. In the list of regression models select [0:ExpReg]
  3. The command ExpReg echoes on main calculator screen.
  4. If you press [ENTER], you'll get your equation but you will not be able to draw the curve on top of your data to verify the goodness (no it is not a swear word) of the fit. So you must save the equation as a function in Y1 variable.
  5. While ExpReg command is still in command line, press the [VARS] key.
  6. Highlight the [Y-VARS] menu and select [1:Function], then press [ENTER].
  7. In the Y function variable list select [1:Y1]
  8. At the command line, you have ExpReg Y1.
  9. Press [ENTER] to save the equation of best fit in Y1.
Here are your results. (These are your actual results)
f07d40f.jpg
You also have r and its square.

Since the equation is saved in the Y1 function it can be superposed on the scatter plot. You just have to press GRAPH and it will be drawn. But that will not tell how good the fit is, until you see the function drawn on top of the raw data.

F. DRAWING THE SCATTER PLOT AND BEST FIT CURVE ON SAME SCREEN

Regardless of the curve of best fit, you can draw a scatter plot as follows.
  1. Press [2nd][Y=] (STATPLOT)
  2. Select [1:Plot1...Off] and press ENTER to open plot1 configuration screen
  3. Use arrow to highlight On and press ENTER
  4. Use the Down Arrow to move cursor to the line Type.
  5. Select the first icon for a scatter plot. NOTE: To navigate the 6 statistical stat plots on the line Type, use the right or left arrow (to backtrack), but not the Up or down arrows.
Here is the configuration screen
b3dea28.jpg
Here plot1 is active (ON), it is scatter plot (first icon) the XLIST is L1 by default but you can change it to some other list. Notice the highlighted A cursor on XLIST line. It means that the [ALPHA] keyboard is active.
On the line Mark you can choose the appearance of the raw data point.

And here are your two graphs: the raw data scatter plot and the line of best fit on the same screen. On the picture the ZoomStat option was used.
d6e8e98.jpg
The graph above represents a parabola and has nothing to do with the sample data entered. But it shows the raw data and the curve of best fit on the same screen.

SOURCE: -6x-3y=27

The x intercept is where your line will cross the x axis. Therefore, the value for y at this point is 0. Substitute 0 for y in this equation and solve for x.

6x + 3(0) = 27
x = 27/6
x = 4 1/2

x intercept = (4 1/2, 0)

Follow the same reasoning for the y intercept.

6(0) + 3y = 27
y = 27/3
y = 9

y intercept = (0,9)

Now plot these two points and draw your line through them.

What is y+x = -4 , graph and find the y-intercept ?


Hey! The standard equation of a straight line is y=mx+b (wherein x&y are the coordinates, m is the slope of the line and, b is the y-intercept). Re-arranging your equation to follow the standard equation, you'll have y= -x - 4 or y=(-1)x + (-4).

To plot the equation, try substituting a number to the (x) coordinate to get the value of the (y) coordinate:
Ex:
If x=0, y= -4
If x=1, y= -5
If x=2, y= -6
If x=3, y= -7
Assuming you know how to plot these coordinates, you now have a graph of the equation. Hope I answered your query. Thank you.

Ind the area of the region bounded by the two circles y=x^3-6x^2+


The first step here is to draw a rough sketch of the two curves, and find the two points they meet. If you set x^3-6x^2+8x = x^3-4x, then you can rearrange this into the quadratic equation 6x^2-12x = 0. Solving this tells you x=0 or 2 : these are the two x values where the curves meet, and they give the bounds on your integral.

When you sketch the curves, you'll see that x^3-4x is below x^3-6x^2+8x, so the thing you need to integrate is (x^3-6x^2+8x)-(x^3-4x), that is, 12x-6x^2. If you integrate this from 0 to 2, you'll have the answer you need!

. x^3 - 4x^2 - 12x


Hii,you can use the following solution x^3 - 4x^2-12x=0 x(x^2-4x-12)=0 replacing -4x from -6x+2x x(x^2-6x+2x-12)=0
Now Factoring x(x(x-6) +2(x-6))=0 x(x-6)(x+2)=0 Solution is x=0, x-6=0,x+2=0 1) x=0 2) x-6=0 =>x=6 3) x+2=0 =>x=-2

What are the steps, when given two coordinates to work out the bearing and distance between them


Let us start by setting the terminology right: To locate a point on a plane you need two coordinates ( an X-value and a Y-value). If the point is in space, you need a third coordinate which may be called z, but let's us not complicate things unecessarily.

With just two coordinates, we will be able to locate at best one point.
Let us rephrase the problem: When given two sets of coordinates, how to calculate the distance between the two points.

Let (x1,y1) and (x2,y2) be the coordinates of two points in a plane. To calculate the distance between the points, one uses the formula
d (distance)= square root of ( (x2-x1)^2+(y2-y1)^2)
a7845a6.jpg
When you calculate the distance you must substitute actual coordinates for X1, Y1, X2 and Y2.

As regards the bearing, I am afraid that I am no expert in maritime nor in aircraft navigation and I will not venture stray out of my area of competence. However, I know that you need an axis that defines the direction with respect to which angles are measured.

If your reference axis is the horizontal axis on a cartesian plane you can determine the angle that the line joining the points makes with that horizontal axis by calculating its cosine, then extract the arcosine.
If (X2-X1) and (Y2-Y1) are both positive then cos(theta)=(X2-X1)/d, where d is the distance (positive value) calculated above.
