In the xy-plane, which point lies in the region defined by y ≥ 2x − 1 but NOT on its boundary line?

Question

Accepted Answer

A. (0, 3). (0, 3): 3 ≥ −1 ✓, and 3 ≠ −1, so it's strictly inside. (1, 1) is ON the line (1 = 2 − 1).

Answer

B. (1, 1) — (1, 1) satisfies 1 = 2(1) − 1, so it is on the boundary, which the question excludes.

Answer

C. (2, 0) — (2, 0): 0 ≥ 3 is false.

Answer

D. (3, 2) — (3, 2): 2 ≥ 5 is false.
