Plug the x and y values in and see which one equals -1. 5x + 2y = -1 A. 5(1) + 2(-3) = 5 = 6 = -1 B. 5(-1) + 2(4) = -5 + 8 = 3 C. 5(2) + 2(-4) = 10 - 8 = 2 D. 5(-2) + 2(5) = -10 + 10 = 0
The easiest way to do this is to plug in the numbers for the variebles and see if they equal the same in both sides. lets try the first one 5(1)+2(-3)=-1, multiply the nmbers to get 5-6=-1 now simplify to get the answer of -1=-1, they both equal the same so this means that the first option is the correct one
