Graphing Linear Inequalities on Number Line

When you graph an inequality, you used a solid line when you use which symbols?

• ≤, ≥ 

• <, >

Will my line be solid?
5 ≥ x

• Yes

• No

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

• It has an equal sign.

• The symbol is greater than.

• The symbol has "or equal to."

• You just guess.

Which inequality represents the solution set shown on the graph above?

Given the graph above, which number is NOT a part of the solution set?

• -2

• -1

• 0

• 1

• x > 2
• x > 5
• x >15
• x > 50

• open circle

• closed circle

• open circle

• closed circle

Solve the inequality

• x ≤ 2

• x ≤ -2

• x ≥ 2

• x ≥ -2

10 ≥ x - 3

• x ≤ 13

• x ≥ 13

• x ≤ 7

• x ≥ 7
