Graphing Inequalities

Showing solutions to linear inequalities graphically with appropriate shading and border designations and testing possible solution points algebraically. Solving word problems that can be modeled by a linear inequality.

Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line). 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 the corresponding half-planes.
