Solving Inequalities on a Number Line

What inequality does the number line graph represent?

• x ≤ 4

• x ≥ -4

• x < -4

• x < 4

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

• ≤, ≥ 

• <, >

Solve the inequality. Don't forget to check your solution set.
12 ≥ 15 - 6y

• y ≤ ½

• y ≤ 2

• y ≥ ½

• y ≥ 2

Which graph matches the inequality
-2 ≥ n?

• A

• B

• C

• D

Match the graph with its inequality. (HINT: don't be tricked by the variable on the right.)

• 11 < a

• 11 > a

•  11 ≤ a

•  11 ≥ a

• v>5 or v<-5
• v≥5 or v≤-5
• v>-5 or v<5
• all real numbers

Would you use a closed or open circle to graph x < 3?

• Closed

• Open

Which graph shows the solution to the inequality:

4x + 10 < 34?

• 
• 
• 
• 

When graphing the solutions to "OR" inequalities, The shading looks like___

• Shading that connects the 2 dots

• Shading that points away and never crosses.

• Shading that points toward each other and ALWAYS crosses

• Shading that points opposite, but sometimes crosses.

3x + 2 < -7 or -4x + 5 < 1

• All real numbers

• x < -3 and x > 1

• x < -3 or x < 1

• x < -3 or x > 1
