(3,1), (1,-15)
-------------
Work left to right, so A = (1,-15) and B = (3,1)
Slope m = (y2-y1)/(x2-x1)
m = (-15-1)/(1-3)
m = 8
--------
Use either point, B is simpler here.
y - y2 = m(x - x2)
y - 1 = 8(x - 3)
y-1 = 8x-24
y = 8x-23 (slope-intercept form, y = mx+b)
-----------
This checks for both points.
