#### To Graph an Inequality Using a Test Point.

- Graph the corresponding equation to obtain the boundary line.
- Choose a test point that does not lie on the boundary line.
- Substitute the coordinates of the test point into the inequality.
- If the resulting statement is true, shade the half-plane that includes the test point.
- If the resulting statement is false, shade the half-plane that does not include the test point.

- If the inequality is strict, make the boundary line a dashed line.
