Question

Which answer is a solution to the inequality?

3x + y > -8

A. (-3, 0)
B. (-2, -1)
C. (0, -10)
D. (2, -16)

Answer 1

B

Explanation:

To determine which ordered pair is a solution, substitute the coordinates of the point into the left side of the inequality and if it satisfies the inequality then it is a solution.

A (- 3, 0 )

- 9 + 0 = - 9 < -8 → (- 3, 0) is not a solution

B (- 2, - 1)

- 6 - 1 = - 7 > - 8 → ( - 2, - 1) is a solution

C (0, - 10)

0 - 10 = - 10 < - 8 → (0, - 10) is not a solution

D (2, - 16)

6 - 16 = - 10 < - 8 → (2, - 16) is not a solution
