Find an equation of the line that has a slope of 2 and a y intercept of -3


A straight line can be written in the form y=mx+b, where m is the slope and b is the y-intercept.

In this case, we are given the slope (2) and the y-intercept (-3).

y=2x-3

Good luck,

Paul

What is the definition of the y intercept?


The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Write the slope intercept form of the equation of the line through the given point (-2, -3), slope=1/2


The "slope intercept form of the equation of a (the) line" is y=mx+b, where m is the slope of the line and b is the y-intercept.

We are given the slope of 1/2, so m= 1/2.

We can now write y=1/2 x + b.

Since the point (-2,-3) is on the line, we can substitute it in and solve for b. We put the -2 in for x and -3 in for y.

-3 = 1/2(-2) +b
-3 = -1 + b
-3 + 1 = -1 + b +1
-2 =b

Thus, the equation of the line is y= 1/2 x -2

To check if we did this correctly, plug in the point (-2, -3) to see if it works.
Left Side Right Side
-3 = 1/2 (-2) -2
= -1-2
= -3

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.

-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.

Find the linear equation in slope-intercept form


The equation of a straight line can be cast into several forms: functional form, general form, symmetrical form. The functional form is the one usually known as slope intercept form.
In the functional form, y=ax+b or sometimes y=mx+b, the factor of the x-variable (a or m as the case may be) is the slope of the straight line, and the value b, is the ordinate (y-value) of the point where the straight line cuts (intercepts) the y-axis.
Since you say nothing about the particulars of the line that interests you, there is not much more that anybody can help you with.

The general answer is no. However the calculator can be used to find the slope and the y-intercept. You write the formula for the rate of change (a) and use the calculator to calculate it. Then you use the formula to find the y-intercept.
If you have 2 points, you can use the 2 -var statistics program to find a linear regression.
