Solve the inequalities graphically in two-dimensional plane: `x-ylt=2`

Explanation

To solve the inequality \( x - y \leq 2 \) graphically in the two-dimensional plane, we will follow these steps:

### Step 1: Rewrite the inequality
We start with the inequality:
\[ x - y \leq 2 \]
This can be rewritten as:
...
