Question

Which of the following points is a part of the solution set for the inequality y > 3х - 1 or y = 3х - 1?(1 point)
(1,1)
(2,5)
(-1, -5)
(-2.5, - 9)

Answer 1

Check which satisfy y ≥ 3x − 1 (since "y > 3x − 1 or y = 3x − 1" means ≥):

- (1,1): 3(1)−1 = 2, but 1 < 2 → no.
- (2,5): 3(2)−1 = 5, and 5 = 5 → yes.
- (−1,−5): 3(−1)−1 = −4, but −5 < −4 → no.
- (−2.5,−9): 3(−2.5)−1 = −8.5, but −9 < −8.5 → no.

Answer: (2, 5).
