### Graphing Inequalities

• The graph of a linear inequality is a half plane bounded by a straight line.

• If the inequality is strict (< or >), then draw the boundary as a dashed line, otherwise draw it as a solid line.

• Use a test point, normally the origin, to determine which half plane is the solution of the inequality. Shade that region.
