Question

What is the solution to the system of equations below y=-3/4x+3 and y=12.

A) (20,-12)
B) (12,-12)
C) (-6,-12)
D) (-12,12)

Answer 1

(-12, 12) D

Explanation:

Substitute y = 12 into the first equation:-

12 = -3/4x + 3

-3/4 x = 12 - 3 = 9

x = 9 * -4/3

= -12

so the answer is (-12, 12)
