# Ch 7: Algebra II: Inequalities Review

Watch online math video lessons and learn about compound inequalities, absolute value inequalities and more. These lessons are just a portion of our high school algebra course.

## Algebra II: Inequalities Review - Chapter Summary and Learning Objectives

Use this chapter to learn how inequalities can be used to describe situations in which there are a range of solutions. You might be surprised at the implications of simply swapping out an equation's equal sign with a less-than or greater-than symbol. Lessons included here can help you examine their graphs and find out what happens when an inequality contains an absolute value. By the time you complete this chapter, you should be able to:

• Solve 1- and 2-variable inequalities
• Graph linear inequalities on a number line
• Graph compound inequalities on the coordinate plane
• Write number sentences describing inequalities

Video Objectives
What Is an Inequality? Examine how inequalities are used in everyday life. Learn how to write 1- and 2-variable inequalities and find out what their graphs look like.
How to Graph 1- and 2-Variable Inequalities Study the processes involved in solving 1-variable linear inequalities and find out how to graph them on a number line. Tips for solving and graphing 2-variable linear inequalities on the coordinate plane are also included.
