Lesson Summary:

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.

Lesson Description:

This is an example of how to graph inequalities in the coordinate plane.

    This lesson goes through an example problem of graphing an inequality in the coordinate plane. You will learn in this lesson how to find the x-intercept and y-intercept of the inequality in standard form, and then you will learn to graph the line and shade. This is another good explanation of how to graph an inequality.
