Question

Which of the following points is a part
of the solution set for the inequality
y ≥ 3x − 1? (1 point)
(−2.5, −9)
(1, 1)
(−1, −5)
(2, 5)

Answer 1

Check each point by plugging into y ≥ 3x − 1.

- (−2.5, −9): 3(−2.5)−1 = −8.5, and −9 ≥ −8.5 is false.
- (1, 1): 3(1)−1 = 2, and 1 ≥ 2 is false.
- (−1, −5): 3(−1)−1 = −4, and −5 ≥ −4 is false.
- (2, 5): 3(2)−1 = 5, and 5 ≥ 5 is true.

So (2, 5) is in the solution set.
