Transcribed Image Text:**Educational Content: Graphing Linear Inequalities**
**Task:**
Analyze the graphs to determine which one represents the inequality \( y > 4x - 3 \).
**Description of Graphs:**
1. **Graph 1:**
- **Line Description:** Solid, diagonal line angled upwards intercepting the y-axis at -3.
- **Shaded Region:** The region to the right of the line is shaded.
2. **Graph 2:**
- **Line Description:** Dashed, diagonal line intercepting the y-axis at -3.
- **Shaded Region:** The region to the right of the line is shaded.
3. **Graph 3:**
- **Line Description:** Solid, diagonal line intercepting the y-axis at -3.
- **Shaded Region:** The region to the left of the line is shaded.
4. **Graph 4:**
- **Line Description:** Dashed, diagonal line intercepting the y-axis at -3.
- **Shaded Region:** The region to the left of the line is shaded.
**Solution:**
The inequality \( y > 4x - 3 \) is represented with a dashed line (since the inequality is strict, ">") with the region above (or to the right of) the line being shaded.
- **Correct Graph:** Graph 2 represents the inequality correctly with a dashed line and shading to the right.

Transcribed Image Text:**Question:**
2. The shaded region of the graph represents which inequality?
**Graph Explanation:**
The graph shows a coordinate plane with a dashed line. The line has a negative slope, crossing the y-axis at (0, 1) and the x-axis at (3.5, 0). The region below the dashed line is shaded, indicating it is the solution region. Since the line is dashed, it represents a non-inclusive inequality.
**Options:**
- ⦿ \(2x + 7y \leq 7\)
- ⃝ \(2x + 7y < 7\)
- ⃝ \(2x + 7y > 7\)
- ⃝ \(2x + 7y \geq 7\)
