Graph the solution to the following system of inequalities.

 

 

**Graphing Solutions to Systems of Inequalities**

To effectively graph the solution to the given system of inequalities, follow these steps:

1. **Identify the inequalities:**
   - \( y > 2x - 5 \)
   - \( y \leq -5x + 2 \)

2. **Graph each inequality on the same coordinate plane:**

   **Graph \( y > 2x - 5 \):**
   - Start by graphing the boundary line \( y = 2x - 5 \). Since the inequality is strict (\( > \)), use a dashed line to represent that points on the line are not included in the solution set.
   - Choose a test point not on the boundary line, typically (0,0) (if it does not lie on the boundary).
   - Substitute (0,0) into \( y > 2x - 5 \):
     \( 0 > 2(0) - 5 \) simplifies to \( 0 > -5 \), which is true.
   - Shade the region above the dashed line, as this is the area where the inequality holds true.

   **Graph \( y \leq -5x + 2 \):**
   - Start by graphing the boundary line \( y = -5x + 2 \). Since the inequality is less than or equal to (\( \leq \)), use a solid line to indicate that points on the line are part of the solution set.
   - Choose a test point not on the boundary line, typically (0,0) (if it does not lie on the boundary).
   - Substitute (0,0) into \( y \leq -5x + 2 \):
     \( 0 \leq -5(0) + 2 \) simplifies to \( 0 \leq 2 \), which is true.
   - Shade the region below the solid line, as this is the area where the inequality holds true.

3. **Identify the solution region:**
   The solution to the system of inequalities is the region where the shaded areas overlap. This region satisfies both \( y > 2x - 5 \) and \( y \leq -5x + 2 \).

**Understanding Graph Intersection:**

Use the graph to determine the intersection of the shaded regions visually. Ensure to pay attention to whether the lines are dashed or solid to correctly
