Graphing Linear Inequalities in Two Variables
A solution to a linear inequality is a point (x, y) that makes the inequality true. The solution set includes all of these points.

Key Idea:
The graph of an inequality in two variables shows all of the solutions of the inequality on a
coordinate plane. The boundary line divides the coordinate plane into two half-planes. A dashed
boundary line means that the solution set does not contain the points on the line. A solid boundary line means that it does. The graph is shaded to
indicate which half plane is included in the solution set.
