First find the slope:
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
m=%28-3--8%29%2F%28-5--7%29
m=%285%2F2%29
slope intercept form is y=mx+b
Plug in 5%2F2 for m. Also plug in the coordinates from one of the points given. We'll use (-5, -3)
-3=%285%2F2%29%28-5%29%2Bb
-3=%28-25%2F2%29%2Bb
9.5=b
the equation is y=%285%2F2%29x%2B9.5
