    No, plug the numbers in: (-3,2) is (x,y) respectively. So you would plug them in: 2=2(-3)+2? Nope that doesn't work. But if you want coordinates that are solutions to this problem it's simple, plug any number you want in for x, for example: 1. y=2(1)+2 so "y" is equal to 4. So your coordinate (now correct) would be (1,4) hope this helps!
