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.

Tutorial

Graphing a system of inequalities has a two step.

1. We need to graph the inequalities as lines.

2. We need to shade the region represented by the inequalities.
