Start with this:

matrix%281%2C3%2C%0D%0A%0D%0Ay-y%5B1%5D%2C%0D%0A%22%22=%22%22%2C%0D%0Am%28x-x%5B1%5D%29%29

Substitute -2 for m
Substitute 4 for x1
Substitute -1 for y1
Do not substitute anything for x, but just leave it as x.
Do not substitute anything for y, but just leave it as y.
Simplify what you get
Solve the equation for y.
