Question
**Graphing the Solution of a System of Inequalities**

**Problem Statement:**

Graph the solution of the system of inequalities:

1. \( y > 3x - 4 \)
2. \( y < 2x + 3 \)

**Graph Representations:**

**A. Graph Details:**

- The graph includes two lines, \( y = 3x - 4 \) and \( y = 2x + 3 \).
- The line \( y = 3x - 4 \) is solid, indicating that the solution may not include the values on this line.
- The line \( y = 2x + 3 \) is solid as well, indicating that the solution might not include the line itself.
- The region of interest (potential solution) does not seem to be shaded in this portion, and hence doesn't show the correct solution set.

**B. Graph Details:**

- Shows the same two lines, \( y = 3x - 4 \) and \( y = 2x + 3 \).
- The line \( y = 3x - 4 \) is dashed, indicating values on this line are not included in the solution.
- The area that may satisfy both inequalities is shaded in green.
- The shading represents the region where the inequality \( y > 3x - 4 \) and \( y < 2x + 3 \) both hold true.
  
**C. Graph Details:**

- Similar to the previous graphs with the lines \( y = 3x - 4 \) and \( y = 2x + 3 \).
- The method of diagramming and shading might differ from B, while still aiming to identify the overlapping region where both inequalities are satisfied.
- It does not clearly represent the correct solution if shading is inconsistent with the given inequalities.

**Graph Interpretation:**

- In graph B, the shading correctly represents the solution region where both inequalities \( y > 3x - 4 \) and \( y < 2x + 3 \) are simultaneously satisfied.
- In checking solutions for systems of inequalities, look for regions where required shading overlaps, with attention to line types (dashed or solid) denoting inclusion or exclusion of boundary lines.

Step 1

y is greater then f(x) then, area is upper size 

If less then, area is lower side
