This lesson covers how to graph inequalities in the coordinate plane, using the example of x + 3y > 24. The transcript walks through finding the x and y intercepts to plot the line, determining whether to use a solid or dotted line, and then shading the correct side of the line to represent the solution set. The lesson emphasizes the importance of checking points to ensure the correct side of the line is shaded.
This is an example of how to graph inequalities in the coordinate plane.
