1 Linear Inequalities Objective: To graph and solve linear inequalities

2 Linear Inequalities Objective: To solve multi-step linear inequalities

3 Review 1.Write the linear inequality for all real numbers greater than or equal to 4. 2.Write the verbal phrase that describes x -2. 3.Is the number 4.78 a solution of x < 5? Is the number 6 a solution of x < 6? 4.Solve the inequality 5 – 2x 3. Then graph it. 1. -2y – 5 < 7 2. 3y – 5 > 7 3. -2y + 3 21 y > -6 y > 4 y -9

4 Multi steps Inequalities Solving and Graphing INEQUALITIES

5 Solving Multi step Inequalities

6 YOUR TURN

7 With Fractions

8 Variables on both sides -3f - 7 -f + 9 +f -2f - 7 9 +7 -2f 16 -2 f -8 Add f on both sides Add 7 on both sides divide -2 on both sides

9 Your turn X > 0 X 2 X > 40 y < 20 y 8y 9
