    To find the solution, just put each point into the equation and if equals -6 then you know it is a solution. I will do the first one. A (-2, -2) 4x + y = –6 4(-2) + (-2) = –6 -8 + -2 = -6 -10 = - 6 -10 does not = -6 so the point A is not a solution. Do the next one, which is B.

    Lets do B (2, -2) B (2, -2) 4x + y = –6 4(2) + (-2) = –6 8 + -2 = -6 6 = - 6 6 does not = -6 so B is not a solution

    It's C because 4(-2)+2=-6 -8+2=-6 -6=-6
