8-8: Exploring Inequalities Foundations for Algebra Mr. Gallo

To Graph a Linear Inequality: 1) Determine the boundary line: Dashed: Points on the line are included. Solid: Points on the line included. 2) Test a point to see where the graph should be shaded: 3) Shade the area of the inequality that is represented by the equation: not are Use an easy point not on the boundary line like (0,0).

Example 1: Graph each linear inequality using the steps outlined above: (0,0)
