Title: Graphing Systems of Linear Inequalities

---

**Objective**: Learn how to graph the following system of linear inequalities.

**System of Inequalities**:
1. \( x - 2y \leq 4 \)
2. \( 2x + 3y \geq 6 \)

**Instructions**:

1. **Graph each inequality separately**:
   - For \( x - 2y \leq 4 \):
     - Rearrange to slope-intercept form: \( y \geq \frac{1}{2}x - 2 \).
     - Graph the line \( y = \frac{1}{2}x - 2 \) using a dashed line (since the inequality is inclusive).
     - Shade the region below the line.

   - For \( 2x + 3y \geq 6 \):
     - Rearrange to slope-intercept form: \( y \geq -\frac{2}{3}x + 2 \).
     - Graph the line \( y = -\frac{2}{3}x + 2 \) using a solid line (since the inequality is inclusive).
     - Shade the region above the line.

2. **Solution Region**:
   - The solution to the system is the region where the shaded areas overlap.
   - Highlight this region to distinguish it from the non-solution areas.

**Practice Exercise**:
- Try graphing another set of inequalities and identify the solution region to reinforce your understanding.
