In this lesson, students learn how to graph and shade linear inequalities in the coordinate plane. They start by understanding how to identify the boundary and then decide whether it's solid or dashed. Next, they test a point to determine the side of the line to shade, either above or below. The teacher emphasizes that the simplest point to use would be (0,0) unless it falls on the line. The lesson concludes with a reminder to always shade the side that makes the inequality true.
