Find an equation for the line that passes through the points (-5,-2) and (1,2)

First we have to find the slope. I use delta y/delta x when doing it from points.

2--2/1--5=4/6=2/3

Now the equation is y=2/3x+b

We just have to find the y-intercept. You can graph it or plug in the points.

Either way, the y-intercept is 1.3 repeating.

The equation is y=2/3x+1.3 repeating.

I hope this helps.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
