Linear Inequality Number Line

What inequality does the number line graph represent?

• x ≤ 4

• x ≥ -4

• x < -4

• x < 4

Solve the inequality.
x + 5 ≤ 13

• x ≥ 8

• x ≥ 18

• x ≤ 8 

• x ≤ 18 

Solve
y - 4 > 12

•  y > 16

• y < 16

• y > 8

• y < 8

If you were to graph x > 2, what would you do?

• put a closed dot on 2 and to the right

• put a closed dot on 2 and to the left

• put an open dot on 2 and to the right

• put an open dot on 2 and to the left

c - 7 > 8

• c < 15

• c > 15

• c < - 15

• c >, = 15

What do you do to solve the graph of the inequality:
     -2x ≤ 10

• divide by -2

• multiply by -2

• multiply by -2 and flip the inequality

• divide by -2 and flip the inequality

Which is the solution of 
-6a ≥ -36

• a ≥ 6

• -6 ≥ a

• a ≤ 6

• 6 ≤ a

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.

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

• ≤, ≥ 

• <, >
