• dotted

• shaded

• unshaded

When graphing the below inequality, which type of line would you use?

• solid

• dotted

• shaded

• unshaded

What inequality does the number line graph represent?

• -x + 3 ≥ 1

• -5x + 3 > -7

• x + 1 < 3

• 5x + 3 ≥ 13

What is the next step to solve this equation? 3x - 5 = 7

• Add 5 to both sides of the equation

• Add 3x to both sides of the equation

• Subtract 5 from both sides of the equation

• Subtract 7 from both sides of the equation
