Steps to Graphing Linear 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. 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.
