Question
**Title: Solving Inequalities through Graphical Interpretation**

**Introduction:**
This page demonstrates how to sketch regions corresponding to a set of inequalities using graphical methods. The inequalities given are:

1. \(18x + 9y \leq 90\)
2. \(9x + 18y \leq 90\)
3. \(9x + 9y \leq 54\)
4. \(x \geq 0\), \(y \geq 0\)

**Graphical Representation:**

The image contains four graphs each illustrating the solution set for the given system of inequalities. Each graph is displayed on the Cartesian coordinate system marked with axes \(x\) and \(y\).

**Description of Graphs:**

- **Graph Layout:**
  - Each graph has labeled axes with tick marks ranging approximately from -10 to 10.
  - The feasible region that satisfies all inequalities is shaded in blue.
  - Lines representing the boundary equations of each inequality are shown, dividing the plane into distinct regions.
  
- **Feasible Solution Set:**
  - The area where all conditions of the inequalities are met (i.e., the "Solution Set") is highlighted.
  - This area represents all the possible values of \(x\) and \(y\) that satisfy the inequalities under given constraints (\(x \geq 0\), \(y \geq 0\)).

By analyzing these graphs, one can visually interpret how different inequalities impose constraints and how they intersect to form the potential solution space. This method helps in understanding the behavior of the system and the range of solutions applicable under given conditions.
