c. is (1, -4) a solution?
_ yes _ no because...

1. is (4, 1) a solution?

_ yes _ no because...

Explanation:

Step1: Recall Solution Region

A solution to the system of inequalities (or equations) represented by the graph lies in the shaded region (or on the boundary, depending on the inequality type). We check if the point lies in the shaded area.

Step2: Check Point (1,1)

The point (1,1) is in the white (unshaded) region of the graph. So it does not satisfy the system's solution conditions.

Answer:

No, because the point (1,1) lies in the unshaded (white) region of the graph, meaning it does not satisfy the system of inequalities (or equations) represented by the graph.
