Definition
A graphed linear inequality shows a boundary line and shading on the side that satisfies the inequality.
Examples
- Graph y > x + 1 with a dashed line, shaded above.
- Use a solid line for <= or >=.
Key rule
Dashed for strict, solid for inclusive; shade the true side.
Memory hook
Dashed or solid line, then shade the winning side.
