1. January , Math 102
OBJECTIVE: Students will be able to solve one step inequalities and graph the solution on a number line
AIM: How is solving an inequality different than solving an equation?
STANDARDS: 7.A.5, 7.G.10
PRIOR KNOWLEDGE: Solve: n + 2n + 7 = 22

2. MINI LESSON:
An inequality is a sentence using either <, >, <, or >
Example
3 + y > 7
Use open circles to graph inequalities that use the signs < or >
Use closed circles that use the signs < or >

3. Example: Solve and graph the inequality y + 2 > 8
Combine like terms
Solve as you would an equation
Graph the solution on a number line
(We use an OPEN CIRCLE…why?)

4. Solve and graph n > -9

5. How do you solve and graph the inequality

6. Which inequalities are graphed below?
X < 5 x < 5 x > 5 x > 5
X > 6 x > 6 x < 6 x < 6

7. HOMEWORK:
On the number line handout, solve and graph these inequalities:
v + 9 > 12
3b < 27
w + 4 > -3
4y < 32
n/6 < 4
b – 4 > 2
