1. 3.3 Notes – Graph Systems of Linear Inequalities

2. When you graph a system of inequalities, where you shade twice is the solution to the system. Dashed lines are used when the inequality isn’t “equal to.” Always solve for y when graphing. Shade in a positive direction when “greater than” and in the negative direction when “less than.”

3. Example #1: Solve each system by graphing.

4. Example #2: Solve each system by graphing.
