1. 9.5 Inequalities in Two Variables  Two Key Terms  Two Objectives

2. Vocabulary Half-plane Boundary Line The region above and below the line The line that separates the half-plane

3. #1 Determine whether the following are solutions

4. #6 Graphing Linear Inequalities x y 7 7 -7 Shade with the point. Boundary Line Half-plane

5. #7 Graphing Linear Inequalities x y 7 7 -7 Shade with the point.

6. #8 Graphing Linear Inequalities x y 7 7 -7 Shade with the point.

7. Steps to Graphing Linear Inequalities 1. Put the inequality into slope-intercept form. 2. Graph the line. 3. See if the line is solid or dashed. 4. Choose a point NOT on the line. 5. Check to see if the point is a solution. 6. Shade the region. Solution: Towards the point Not a Solution: Away from the point
