Question

7) Which ordered pair is a solution of the equation 3y – 2 = 8x + 5? *

A) (1, 5)
B) (3, 9)
C) (–4, 9)
D) (–2, 3)

Answer 1

If you plug in the values with their respective x and y variables you can find out.

For (1, 5):
3y - 2 = 8x + 5
3(5) - 2 = 8(1) + 5
15 - 2 = 8 + 5
13 = 13

This is indeed correct because 13 equals 13.
