**Which point is in the solution set for question 9?**

1. \( y \leq -2x + 5 \)

2. \( y \geq \frac{3}{2}x - 2 \)

*Explanation:*

We are tasked with finding a point that satisfies both inequalities. This requires identifying a coordinate \((x, y)\) such that it lies within the shaded region where these two lines intersect on a graph.

1. **First Inequality:**
   - The inequality \( y \leq -2x + 5 \) represents a line with a slope of \(-2\) and a y-intercept of \(5\). The region of interest is below this line.

2. **Second Inequality:**
   - The inequality \( y \geq \frac{3}{2}x - 2 \) represents a line with a slope of \(\frac{3}{2}\) and a y-intercept of \(-2\). The region of interest is above this line.

For a point to be in the solution set, it must satisfy both conditions, lying below the first line and above the second line. Visual graphing tools or manual calculation would help in identifying such a point.
