Solving Inequalities

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

• <, >
• ≤, ≥ 

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

• ≤, ≥

• <, >

Match the graph with its inequality.

• 11 < a

• 11 > a

• 11 ≤ a

• 11 ≥ a

• x > 4
• x > 9
• x < 3
• x < 4
