Which ordered pair is a solution to the equation? 2y = −5x – 4

Question

Answer choices:

(1,-4)

(0,2)

(-1,1)

(-2,3)

Answer 1

The only way to find out is to plug the choices in and see if the equation balances out:

2 * -4 = -5 * 1 - 4

-8 = -5 - 4 → -9, so no.

2 * 2 = -5 * 0 - 4

4 = 0 - 4 → -4, so no

2 * 1 = -5 * -1 - 4

2 = 5 - 4 → 1, so no

2 * 3 = -5 * -2 - 4

6 = 10 - 4 → 6, so yes
