Solving Systems of Inequalities Algebraically

Objectives:
Students will derive a method to determine the domain of the solution set for a system of linear inequalities and will practice using it.

NCTM Standards:
Students select and use various types of reasoning and methods of proof.
Students select, apply, and translate among mathematical representations to solve problems.

California Content Standards:
