Solve graphically the system of linear equations
x + y = 10 and x - y = 4.

Explanation

To solve the system of linear equations \( x + y = 10 \) and \( x - y = 4 \) graphically, we will follow these steps:

### Step 1: Plot the first equation \( x + y = 10 \)

1. **Find the intercepts**:
- Set \( x = 0 \):
\[
0 + y = 10 \implies y = 10 \quad \text{(Point: (0, 10))}
