Solving One-Step Inequalities & Graphing Inequalities

Graphing Inequalities

• < and > have open circles

• ≤ and ≥ have closed circles

Multiple Choice

What inequality does the number line graph represent?

• x≥ 3

• x > 3

• x < -3

• x ≤ 3

Multiple Choice

Pick the correct inequality.

• A

• B

• C

• D

6x ≤ 18

• Since the operation in the inequality is multiplication, we will use division to solve.

• Divide both sides of the inequality sign by 6

• 18 divided by 6 equals 3

• x≤3

• If we were to graph this, the circle would be closed!

• Since the operation in the inequality is division, we will use multiplication to solve.

• Multiply both sides of the inequality sign by 5.

• 4 times 5=20

• x>20

• If we were to graph this, the circle would be open!

Multiple Choice

• x<4

• x≤1

• x≤4

• x≥1

Multiple Choice

• m>7

• m≤5

• 5>m

• 5<m
