Lesson Summary:

Solving and Graphing Inequalities is a beginner's guide to understanding linear inequalities and how to solve them. The lesson takes you step by step through the process of isolating letters and numbers on either side of the inequality sign. You will learn how to graph the inequalities on a number line, and how to interpret the results. The lesson also explains how to solve separate statements and graph them together in a logical manner.

Lesson Description:

Learn how to solve linear inequalities and graph them on a number line.
