### Graphing the Feasible Region for a System of Inequalities

**System of Inequalities:**
1. \( x + 2y \leq 8 \)
2. \( 2x + y \leq 8 \)
3. \( x \geq 0 \)
4. \( y \geq 0 \)

**Instructions:**
Use the graphing tool on the right to plot the system of inequalities.

**Graph Explanation:**
- The graph is a coordinate plane with the x-axis and y-axis, each ranging from -10 to 10.
- You are instructed to graph the feasible region for the given system of inequalities.
- The x-axis and y-axis intersect at the origin (0,0).
- The inequalities \( x \geq 0 \) and \( y \geq 0 \) mean the feasible region will be in the first quadrant, where both x and y are non-negative.

### How to Graph:

1. **Inequality 1: \( x + 2y \leq 8 \)**
   - Graph the line \( x + 2y = 8 \) first, then shade below this line.

2. **Inequality 2: \( 2x + y \leq 8 \)**
   - Graph the line \( 2x + y = 8 \) first, then shade below this line.

3. **Inequality 3 and 4:**
   - Since \( x \geq 0 \) and \( y \geq 0 \), shade the portion of the graph that is in the first quadrant.

**Additional Features:**
- The instructions mention a button "Click to enlarge graph," indicating that users on the website can view a larger version of the graphing tool for better visibility and interaction.
  
This graphing activity helps in understanding the visual representation of solutions for a system of linear inequalities. The feasible region is the intersection area that satisfies all given inequalities.
