When graphing an inequality, you use an open dot when you use which symbol?

• <, >
• ≤, ≥ 

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

• ≤, ≥ 
• <, >

Match the graph with its inequality.

• 11 < a
• 11 > a
•  11 ≤ a
•  11 ≥ a

Solve: -2x ≤ 14

• x ≤ 7
• x ≤ -7
• x ≥ 7
• x ≥ -7

You flip an inequality symbol when you...

• subtract
• multiply and divide only
• multiple by a negative number
• multiple or divide by a negative number

Solve for k. 

7k – 2 ≥ -9

• k ≤ -1
• k≤1
• k≥1
• k ≥ -1

Solve for k.
2k - 9≤ -19

• k ≤ -5
• k ≤ 5
