Answer: y=-5/4x-3

First, find the slope of the line. You can use the distance formula to find it. The distance formula is Y2-Y1/X2-X1. When you plug in the points, 2-(-8)/-4-4=-10/8=-5/4. So far the equation is y=-5/4x+b. To find the value of b, you can plug in one of the points and solve. I will use (-4,2). When you plug in that point you get 2=5+b, b=-3. So, the equation is y=-5/4x-3
