Explanation:

You could do this in your head, but I'm going to type out everything.

Also, you're going to have to just test these out, there is no short cut for this sort of problem.


2(-2)-4(-3)=2\\-4+12=2\\8\\eq 2\\\\2(-3)-4(-2)=2\\-6+8=2\\2=2

I didn't do the last ordered pair because we already found one that fit the equation. Also, it wouldn't be a 1:1 equation if that last one was true, so you can rule it out once you see that (-3,-2) is the correct answer.

Answer:

(-3,-2)
