%28y-y%5B1%5D%29%2F%28y%5B2%5D-y%5B1%5D%29=%28x-x%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
Points (-12,8) and (10,-3)
substitute x%5B1%5D=-12, y%5B1%5D=8, x%5B2%5D=10, y%5B2%5D=-3
%28y-8%29%2F%28-3-8%29=%28x-%28-12%29%29%2F%2810-%28-12%29%29
%28y-8%29%2F-11=%28x%2B12%29%2F22multiply by (-22)
2%28y-8%29=-%28x%2B12%29
2y-16=-x-12
2y=-x-12%2B16
2y=-x%2B4divide by 2
y=-%281%2F2%29x%2B2
The y intercept is (0,2)
