Transcribed Image Text: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.
