1. **State the problem:** We need to solve the system of inequalities graphically:
$$y < -\frac{1}{3}x - 3$$
$$y \leq x + 5$$
and find a point in the solution set.
2. **Understand the inequalities:**
- The first inequality is a strict inequality $y < -\frac{1}{3}x - 3$, meaning the solution region is below the line $y = -\frac{1}{3}x - 3$ (not including the line).
- The second inequality is $y \leq x + 5$, meaning the solution region is on or below the line $y = x + 5$.
3. **Graph the boundary lines:**
- For $y = -\frac{1}{3}x - 3$, the line has slope $-\frac{1}{3}$ and y-intercept $-3$.
- For $y = x + 5$, the line has slope $1$ and y-intercept $5$.
4. **Determine the solution region:**
- Shade below the line $y = -\frac{1}{3}x - 3$ (not including the line).
- Shade on or below the line $y = x + 5$.
5. **Find the intersection point of the boundary lines:**
Set
$$-\frac{1}{3}x - 3 = x + 5$$
Multiply both sides by 3 to clear the fraction:
$$3\left(-\frac{1}{3}x - 3\right) = 3(x + 5)$$
$$\cancel{3}\left(-\frac{1}{\cancel{3}}x\right) - 9 = 3x + 15$$
$$-x - 9 = 3x + 15$$
Add $x$ to both sides:
$$-9 = 4x + 15$$
Subtract 15 from both sides:
$$-9 - 15 = 4x$$
$$-24 = 4x$$
Divide both sides by 4:
$$\frac{-24}{\cancel{4}} = \frac{4x}{\cancel{4}}$$
$$-6 = x$$
6. **Find $y$ coordinate:**
Substitute $x = -6$ into $y = x + 5$:
$$y = -6 + 5 = -1$$
So the lines intersect at $(-6, -1)$.
7. **Choose a test point in the overlapping shaded region:**
Try $(-7, -2)$:
- Check $y < -\frac{1}{3}x - 3$:
$$-2 < -\frac{1}{3}(-7) - 3 = \frac{7}{3} - 3 = \frac{7}{3} - \frac{9}{3} = -\frac{2}{3}$$
Is $-2 < -\frac{2}{3}$? Yes.
- Check $y \leq x + 5$:
$$-2 \leq -7 + 5 = -2$$
Yes, equality holds.
Therefore, $(-7, -2)$ is in the solution set.
**Final answer:** A point in the solution set is $\boxed{(-7, -2)}$.
