To solve the system of inequalities by graphing:
1. **Graph the first inequality \( y \leq -\frac{1}{3}x + 7 \)**:
- Plot the line \( y = -\frac{1}{3}x + 7 \) with a dashed line.
- Shade the area below the line.
2. **Graph the second inequality \( y \geq -x + 3 \)**:
- Plot the line \( y = -x + 3 \) with a solid line.
- Shade the area above the line.
3. **Find the overlapping shaded region**:
- This area represents the solution to the system of inequalities.
If you need help with graphing, consider using graphing software or graph paper to visualize the solution.

It seems that the graphing tool is currently unavailable. However, I can guide you through the process of solving the system of inequalities by graphing them step by step.
### Step 1: Graph the first inequality
The first inequality is:
\[
y \leq -\frac{1}{3} x + 7
\]
1. **Find the y-intercept**: Set \(x = 0\):
\[
y = -\frac{1}{3}(0) + 7 = 7
\]
So, the y-intercept is (0, 7).
2. **Find another point**: Set \(y = 0\) to find the x-intercept:
\[
0 = -\frac{1}{3} x + 7 \implies \frac{1}{3} x = 7 \implies x = 21
\]
So, the x-intercept is (21, 0).
3. **Draw the line**: Plot the points (0, 7) and (21, 0) and draw a dashed line since the inequality is "less than or equal to" (the line itself is included).
4. **Shade the region**: Shade below the line because \(y\) is less than or equal to the line.
### Step 2: Graph the second inequality
The second inequality is:
\[
y \geq -x + 3
\]
1. **Find the y-intercept**: Set \(x = 0\):
\[
y = -0 + 3 = 3
\]
So, the y-intercept is (0, 3).
2. **Find another point**: Set \(y = 0\) to find the x-intercept:
\[
0 = -x + 3 \implies x = 3
\]
So, the x-intercept is (3, 0).
3. **Draw the line**: Plot the points (0, 3) and (3, 0) and draw a solid line since the inequality is "greater than or equal to" (the line itself is included).
4. **Shade the region**: Shade above the line because \(y\) is greater than or equal to the line.
### Step 3: Identify the solution region
The solution to the system of inequalities is the region where the shaded areas overlap. This region represents all the points \((x, y)\) that satisfy both inequalities.
If you have graphing software or graph paper, you can plot these lines and shade the appropriate regions to visualize the solution. If you need further assistance or have any questions, feel free to ask!
