Graphing Linear Inequalities

Author: Jiawei Liu


12. Graph the solutions to a linear inequality in two variables as a half-plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of corresponding half-planes.
