Question

which of the following ordered pairs is a solution of the equation -2y + 9 = -x? A.(2,5) B.(-3,15) C.(4,-1)

Answer 1

Explanation:

-2y + 9 = -x

x - 2y = -9

Plug in each set of points and see if the equation holds true.

A. 2 - 2(5) = ?

B. -3 - 2(15) = ?

C. 4 - 2(-1) = ?

I don't think that any of them work.
