Chapter 9 Focuses on inequalities building on the knowledge of solving equations . Using the solutions to equations gives a boundary for inequalities. Both single variable inequalities , inequalities in the plane, and systems of inequalities are explored.

Checkpoint Review: Students master different skills at different speeds. No two students learn exactly the same way at the same time. At some point you will be expected to perform certain skills accurately. Most of the Checkpoint problems incorporate skills previously developed. Each chapter has a different skill that should be mastered.
