1. **State the problem:** We need to solve the system of inequalities graphically:
$$y \leq \frac{1}{2}x - 6$$
$$y \geq x + 3$$
and find a point in the solution set.
2. **Understand the inequalities:**
- The first inequality represents all points on or below the line $$y = \frac{1}{2}x - 6$$.
- The second inequality represents all points on or above the line $$y = x + 3$$.
3. **Graph the boundary lines:**
- For $$y = \frac{1}{2}x - 6$$, slope is $$\frac{1}{2}$$ and y-intercept is $$-6$$.
- For $$y = x + 3$$, slope is $$1$$ and y-intercept is $$3$$.
4. **Find the intersection point of the two lines:**
Set $$\frac{1}{2}x - 6 = x + 3$$.
$$\frac{1}{2}x - 6 = x + 3$$
Subtract $$\frac{1}{2}x$$ from both sides:
$$\cancel{\frac{1}{2}x} - 6 = \cancel{x} + 3 - \frac{1}{2}x$$
which simplifies to:
$$-6 = \frac{1}{2}x + 3$$
Subtract 3 from both sides:
$$-6 - 3 = \frac{1}{2}x + \cancel{3} - 3$$
$$-9 = \frac{1}{2}x$$
Multiply both sides by 2:
$$2 \times (-9) = 2 \times \frac{1}{2}x$$
$$-18 = x$$
5. **Find corresponding y-coordinate:**
Substitute $$x = -18$$ into one of the lines, for example $$y = x + 3$$:
$$y = -18 + 3 = -15$$
6. **Solution set:**
The solution set is the region where $$y \leq \frac{1}{2}x - 6$$ and $$y \geq x + 3$$ overlap.
7. **Example point in solution set:**
The intersection point $$(-18, -15)$$ lies in the solution set.
**Final answer:**
A point in the solution set is $$\boxed{(-18, -15)}$$.
