Graphing Inequalities in Two Variables

1. Find the boundary by graphing the equation related to the inequality. If the inequality symbol is < or >, draw the boundary as a dashed line. If the inequality symbol is or , draw the boundary as a solid line to show that the points on the boundary are included in the solution set.
2. Determine which of the two half-planes contains the solutions by choosing a point in each half-plane and testing its coordinates in the inequality. If the coordinates make the inequality true, shade that half-plane.
