y<2/3x+2
O (0, 3)
O (-3, 1)
O (3,5)
O (1, 2)

Answer 1

Answer: D

Explanation:

We can substitute in each of the coordinate pairs.

A) We get 3 < (2/3)(0)+2, which is false.

B) We get 1 < (2/3)(-3)+2, which is false.

C) We get 5 < (2/3)(3)+2, which is false.

D) We get 2 < (2/3)(1)+2, which is true.
