Graphing Linear Inequality Review

Johnny earns $15 per hour dog walking. He wants to earn at least $105 to buy a new bike. Which inequality represents how long Johnny needs to work to afford his new bike?

• 15h ≤ 105

• 15h > 105

• 15h < 105

• 15h ≥ 105

Answer explanation

Johnny needs to work at least 7 hours (15h ≥ 105) to afford his new bike.

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

• ≤, ≥ 

• <, >

• ≤, <

• ≥, >

Match the graph with its inequality.

• b > –2

• b < –2

• b ≥ –2

• b ≤ –2
