Chapter 5 Linear Inequalities Review

How can I tell if the graph of an inequality will have a solid line?

• It has just an equal sign.

• The symbol is greater than.

• The symbol has "or equal to."

• You just guess.

Which point below is NOT part of the solution set?

• (0, 0)
• (-10, -10)
• (-1, 5)
• (5, 20)

Select the graph for y ≥ -3.

• A
• B
• C
• D

Which point below is NOT part of the solution set?

• (0, 0)
• (-10, -10)
• (-1, 5)
• (5, 20)

Select the graph for 5x+ y ≤  -1 .

• A
• B
• C

When graphing a linear inequality, < and > signs would require you to draw...

• a solid line

• a dotted line

• a solid line

• a dotted line

Identify the y-intercept for the function:
y=-3x

• -3
• 0
• 1
• -1

Solve for t.

6t + 4 ≤ -2

• t ≤ -1 
• t ≤ 1
• t=1
• 1=t
