The answer is (-1,-2)

First, we put the equation in standard form
Add the 2x to the other side leaving us with -y = 2x +4. They y must be positive so we multiply the whole equation by -1. This gives us y = -2x - 4. We then plug the coordinates in to find out which one comes out to be true.

The only one that comes out true is (-1,-2)
-2 = -2(-1) - 4 which comes out to -2 = -2 True.
