You needed to use,
y-y%5B1%5D=%28%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29%29%28x-x%5B1%5D%29
or
y-y%5B2%5D=%28%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29%29%28x-x%5B2%5D%29
.

.
y-1=%28%28-1-1%29%2F%280-%28-3%29%29%29%28x-%28-3%29%29
y-1=%28%28-2%29%2F%283%29%29%28x%2B3%29
y-1=-%282%2F3%29x-2
y=-%282%2F3%29x-1
