Graphing Linear Inequalities

Skill Practice!

Determine which ordered pairs are part of the solution set for each inequality.
1. y > 3x, {(1, 5), (1, 0), (-1, 0), (5, 1)}

2. y > x + 3, {(2, -3), (-2, -1), (1, 6), (3, 4)}

3. y < x – 1, {(3, 1), (-2, -4), (4, -2), (-3, 3)}

Match each inequality with its graph.

4. y – 2x < 2 a. b.

5. y < –3x

6. 2y – x > 4
c. d.
7. x + y > 1

Graph each inequality.

8. y < – 1 9. y > x – 5 10. y > 3x
