1. Solve, then check your solution. 0 77 0 – 12 > 65 – 12 > 65 Example 1-1a

2. Solve and graph y21 0 21 Example 1-2a

3. Solve, then graph the solution. -9 0 Example 1-3a

4. Solve Seven times a number is greater than six times that number minus two. Seven timesa number is greaterthan six timesthat number minus two. 7n 6n 2 > – Example 1-5a

5. True or False? 5 > -3 True Now multiply both sides by 2 5 > -3 2(5) > 2(-3) 10 > -6 True True or False? 5 > -3 True Now multiply both sides by -2 5 > -3 -2(5) > -2(-3) -10 > 6 False

6. 5 > -3 2(5) > 2(-3) 5 > -3 -2(5) > -2(-3) 10 > -6 True -10 6 > < False True If you multiply or divide both sides of an inequality by a negative number, reverse the inequality sign.
