  1. 8-8: Exploring Inequalities Foundations for Algebra Mr. Gallo

  2. To Graph a Linear Inequality: • Determine the boundary line: Dashed: Points on the line are included. Solid: Points on the line included. • Test a point to see where the graph should be shaded: • 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).

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

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

  5. Example 2: Give the inequality for each graph below. Slope =_________ y-intercept =_________ Inequality =______________

  6. Example 2: Give the inequality for each graph below. Inequality =______________
