Two Variable Inequalities from their Graph

This video introduces the idea of finding the two variable inequality from the graph. The general strategy is to use slope intercept form to determine the boundary line. Then use the shading and whether the line is dashed or solid to determine the correct inequality symbol. Khan Academy exercise to practice: 1.
