The image shows a system of two equations that need to be solved graphically. Here's the system of inequalities provided:

\[
y \geq x - 3
\]
\[
y \leq -\frac{1}{2}x - 1
\]

We are asked to find the coordinates of a point in the solution set.

### Step-by-step solution:

1. **Graph the first inequality** \( y \geq x - 3 \):
   - The line equation is \( y = x - 3 \).
   - The slope is 1 and the y-intercept is -3.
   - The inequality \( y \geq x - 3 \) means we shade the region above the line.

2. **Graph the second inequality** \( y \leq -\frac{1}{2}x - 1 \):
   - The line equation is \( y = -\frac{1}{2}x - 1 \).
   - The slope is \( -\frac{1}{2} \) and the y-intercept is -1.
   - The inequality \( y \leq -\frac{1}{2}x - 1 \) means we shade the region below the line.

3. **Intersection of the two regions**:
   - The solution set is the region where both inequalities overlap.
   - To find this, we can solve the system algebraically to find the boundary point where the two lines intersect.

### Solving the system algebraically:
Set the equations of the two lines equal to each other:
\[
x - 3 = -\frac{1}{2}x - 1
\]
Multiply the entire equation by 2 to eliminate the fraction:
\[
2(x - 3) = -(x + 2)
\]
This simplifies to:
\[
2x - 6 = -x - 2
\]
Add \(x\) to both sides:
\[
3x - 6 = -2
\]
Add 6 to both sides:
\[
3x = 4
\]
Divide by 3:
\[
x = \frac{4}{3}
\]

Substitute \(x = \frac{4}{3}\) back into one of the original equations to find \(y\). Let's use \(y = x - 3\):
\[
y = \frac{4}{3} - 3 = \frac{4}{3} - \frac{9}{3} = -\frac{5}{3}
\]

Thus, the lines intersect at the point \(\left(\frac{4}{3}, -\frac{5}{3}\right)\).

This is the boundary point of the solution set, but the actual solution includes all points in the shaded region above and below the lines.
