Module 7: Solving Linear Inequalities
In earlier math courses, you used inequality symbols to describe the relationship between values that are not equal. For example, 2 < 3. You also solved linear inequalities in one variable. For example, x − 6 ≥ 1. In this module, you will build upon your knowledge of linear inequalities and learn how to:
- apply the properties of inequality to solve multi-step linear inequalities, in one and two variables,
- use the graphing calculator to determine solution sets of linear inequalities,
- solve problems involving systems of inequalities, and
- solve practical problems involving inequalities.
