Solving Two Step Inequalities and Graph

Match the graph with its inequality.

• b > –2

• b < –2

• b ≥ –2

• b ≤ –2

When solving inequalities, when do you flip the inequality symbol?

• When the solution is a negative.

• When you multiply or divide both sides of the inequality by a negative number.

• When you multiply both sides of the inequality by any number.

• When you divide both sides of the inequality by a positive number.

Do I need to flip my sign when I solve this inequality?

• Yes

• No

Solve for k. 2k - 9 ≤ -19

• k ≤ -5

• k ≤ 5

• k < -5

• k < 5

Solve for x.

2x + 6 ≥ -8

• x ≥ -7

• x ≤ -7

• x ≥ -10

• x ≤ -10

Solve for k.

7k – 2 ≥ -9

• k ≤ -1

• k ≤ 1

• k ≥ 1

• k ≥ -1

Do I need to flip my sign?

-3x ≥ 12

• Yes, because I'll be dividing by a negative number

• No, because you never flip the sign.

When you graph an inequality, you use a closed dot when you use which symbols?

• ≤, ≥ 

• <, >

• ≤, <

• ≥, >

Which graph matches the inequality

• A

• B

• C

• D

y + 7 ≥ 12

• y ≥ 5

• y ≤ 5 

• y ≥ 19 

• y ≤ 19
