Answer 1

To solve the given system of inequalities graphically, we need to plot each inequality on a Cartesian plane.

### Step 1: Plot the inequalities

1. **Inequality 1: \(y \leq x - 2\)**

- First, plot the line \(y = x - 2\). This line has a slope of 1 and a y-intercept of -2.
- The line divides the plane into two regions. Since the inequality is \(y \leq x - 2\), we shade the region below this line.

2. **Inequality 2: \(y \leq -\frac{1}{2}x - 5\)**

- Plot the line \(y = -\frac{1}{2}x - 5\). This line has a slope of -1/2 and a y-intercept of -5.
- Again, since the inequality is \(y \leq -\frac{1}{2}x - 5\), shade the region below this line as well.

### Step 2: Identify the solution set

The solution set is the region where the shaded areas from both inequalities overlap.

### Step 3: Find an intersection point (optional for graphical solution)

To find a point in the solution set, we can look for points of intersection between the two lines.

1. Set the equations equal to find their intersection:
\[
x - 2 = -\frac{1}{2}x - 5
\]
\[
2x - 4 = -x - 10 \implies 3x = -6 \implies x = -2
\]
\[
y = -2 - 2 = -4
\]
Thus, the intersection point is \((-2, -4)\).

### Conclusion

The intersection point \((-2, -4)\) lies in the solution set since it satisfies both inequalities.

**Final Answer:** The coordinates of a point in the solution set are \((-2, -4)\).
