Essential Question How do I solve and graph linear inequalities?

Review solving linear inequalities When do you reverse the sign of the inequality and why? Given two inequalities like –5 5, is each inequality still true if: 1. You add 2 to each side? 2. You add –2 to each side? 3. You multiply each side by 2? 4. You multiply each side by –2?

Solve Compound Inequalities 1.) -3 < 2x + 1 < 5 2.) -7 < 2 – 3x < 5
