Answer:

B and C

Step-by-step explanation:

To determine which ordered pairs are a solution, substitute the coordinate points into the left side of the inequality and check against right side for validity.

A (3, 5)

25 - 9 = 16 ≥ 7 ⇒ (3, 5) is not a solution

B (- 2, - 5)

- 25 + 6 = - 19 ≤ 7 ⇒ (- 2, - 5) is a solution

C (5, - 3)

- 15 - 15 = 0 ≤ 7 ⇒ (5, - 3) is a solution
