Can I work graphing problems using the intercept method with the TI-30XA?

How can you graph equations (functions) if you do not have a graphing calculator?

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

The first solution will allow you to watch your
calculator graph two equations simultaneously rather than finishing one
before graphing the next; it won't solve the problem of having the
calculator unselect one equation when you select a second. To fix
that problem, try the following:

In order to select additional graphs, the Transformation Graphing App
will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus
Family. Uninstalling the App does not erase it from the calculator, it
disables it from interfering with the normal graphing modes. Below are
the steps to successfully uninstall the App.

- Press [APPS] key
- Select Transfrm from the menu
- Press 1:Uninstall

SOURCE: Graph feature is not working on TI-83

you have one of your stat plots on that is what is messing it up. So either turn off the stat plots. Or just reset your calculator. hit 2nd then the plus (+) key then 7 then 1 then 2. Good luck

Use the inverse log key sequences "2nd LN" or "2nd LOG" depending on whether you are using natural logs or logs to base 10

or press ZOOM, option 6 (ZStandard). That instantly resets the window range.

go to apps menu, go to transform app. click uninstall and go to y= screnn and should be a slash on the left and you should be able to graph more than one equation.

The easiest way to solve and graph and equation is to put the equation into the slope intercept form y = mx + b, where m is the slope and b in the y-intercept.

To do this, we subtract 4x from both sides and get y = -4x + 0.

From this we know m = -4 (slope) and the y-intercept is 0.

I always start with the y-intercept and put a point there. Thus, we have a point at (0,0). Using this as a starting point, we now use the slope of -4 to get future points. Since it is negative, we go one unit to the left and up four units. So we have the point (-1,4). Using a ruler, we connect these points and continue on both sides to produce the line.

There is also a great free online program/app called Desmos that you can use to check your work. Type in the equation of the line and it will graph it for you.

Good luck,

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

Use the definitions of the intercepts.

x-intercepts (or zeros or roots) are the values of the independent variables that make the function equal to zero. To obtain an intercept set y=0 in equation : 5x=-10, mean x=-10/5=-2

y-intercept: value of y when x=0.

Just set x=0 in equaltion and solve for y

-4y=-10, gives y=5/2

And Sorry, I cannot enter the answer in the drop box.

x-intercept (or zero of the function)

Set y=0 in the equation and solve fo x: 2x-5(0)=20 and x=20/2=10

y-intercept (initial value)

Set x= 0 in the equation and solve for y: 2(0)-5y=20 and y=20/(-5)=-4

If the equation is in the slope-intercept form y=ax+b

1. y-intercept is b

2. To get the x-intercept ( zero of the function) Set y=0=ax+b, and x=-b/a

Set y=0 in the equation and solve fo x: 2x-5(0)=20 and x=20/2=10

y-intercept (initial value)

Set x= 0 in the equation and solve for y: 2(0)-5y=20 and y=20/(-5)=-4

2. To get the x-intercept ( zero of the function) Set y=0=ax+b, and x=-b/a

The TI-30XA is not a graphical calculator. You can use it to calculate the function at different values of the argument and then plot the points on a sheet of graph paper, but you're not going to see a graph on its screen.

use the slope-intercept form to graph y=2/3x+4

Mar 31, 2010 | Computers & Internet

The equation of a straight line is given by y=mx + b where y if the y intercept on a graph and x is the x intercept on a graph and m is the slope of the line

Using the given information of ( -4, 6), m=8

-4 is the x intercept, 6 is the y intercept and the slope is 8.

Plugging these values into the y = mx + b gives 6 = (8) (-4) + b solving for b gives b = 32

Going back to the original equation of a straight line gives the equation of y = 8x + 32

Hope this helps Loringh PS Please leave a rating for me Thank you

Srry my friend the ti 83 is no magnificent Ti-89. meaning: you have to solve it yourself. There is a method for graphing though. Set the equation equal to zero and then plug the stuff on the other side of the equation into a graph by pressing y= and then typing it in. Then hit graph. Wait for the graph and then hit 2nd calc and select zeros. Bring your cursor using hte arrow keys close to where the line hits the x axis and press enter and then do the same except to the right of that point and then press enter twice and it will display the y which should be the answer

There are quadratic formulas for calculators programmed in tibasic for the calc but other than that there is no way to solve it
