Introduction to Step Inequalities

When graphing an inequality, you use an open dot when you use which symbol?

• <, >
• ≤, ≥ 

What inequality does the number line graph represent?

• x ≤ -4
• x ≥ -4
• x < -4
• x < 4

Solve for t.

6t + 4 ≤ -2

• t ≤ -1 
• t ≤ 1
• t=1
• 1=t

Which number is a possible solution to the inequality below?
12 - m ≤ 7

• 8
• 9
• 5
• all three are possible solutions

-9a - 1 < 26

• a<-3
• a<3
• a>-3
• a>3

16 - 4a > 8

• a<-2
• a>-2
• a<2
• a>2

Level 1

When do we switch the inequality symbol?

• when multiplying or dividing by a NEGATIVE

• when adding and subtracting a NEGATIVE

• we never switch the inequality

• When there is a negative in the problem

Level 2

-4 + y < -8

• y < 4

• y < -12

• y < -4

• y < 12

Level 3

Solve

-5m < 10

• m < -2

• m > -2

• m < -50

• m > -50

Pick the correct letter for:
6 > x

• A
• B
• C
