Which of the following ordered-pairs is NOT a solution to the linear inequality graphed?

• (-3, 2)

• (6, -3)

• (4, -7)

Answer explanation

Solutions to linear inequalities are ordered-pairs within the shaded region of a graph.

If the line is solid, the ordered-pairs ON the line are also solutions.

If the line is dashed, the ordered-pairs ON the line are NOT solutions.
