2.8 Two Variable Inequalities Target: I can graph two variable inequalities

Steps to Graphing Inequalities 1. Change the inequality into slope-intercept form, y = mx + b. Graph the related equation. 2. If > or < then the line should be dashed. If > or < then the line should be solid. 3. Use a test point (0,0) if available. (If y > mx+b or y > mx+b, shade the half plane above the line. If y < mx+b or y < mx+b, shade the half plane below the line.)
