1. 8.7 Solving Inequalities
Objective: Students will solve one-step inequalities and graph them on the number line. Students will be able to describe what each answer and graph means.

2. Solve inequalities n + 8 > 3 x – 8 < 23 10 ≥ y + 4

3. St.Examples
x + 2 > 3
1 ≤ x – 9
x + 4 < 3
-6 ≤ x - 9

4. Graphing Inequalities
x + 4 < 5
m + 8 ≥ 12
z – 15 ≥ 65
h + 19 < 15

5. St. Examples
f + 1 ≤ 6
z – 15 > 72
d - 8 < 7
d – 7 ≤ -8

6. Notes
When dividing or multiplying by negative number, switch inequality sign.
Ex: -2x < 6
-2x > 6

7. Inequality (division)
2x > -8
-7s ≤ 14
5a < 35
5z ≥ -65

8. Student Examples
9a < 36
12x ≤ -60
-7s > -84
-16k > 32

9. Inequality (multiplication)

10. Inequality (multiplication)
B / 7 > 21
N / -3 ≥ -5
t/9 > 12
u/5 < 12
