Reread Each Inequality
Mentally put on the brakes if you see an inequality sign . Stop and think about the
meaning of the symbol. Then reread the
whole inequality, substituting the word
form of the symbol as you read
If inequality symbols confuse you, then
write each symbol with its meaning on the
inside cover of your notebook for quick
reference. Sketch a graph if that will help
Questions 1. Write the word form of each inequality.
a. x < 2y
b. x ≥ 9
c. 2x > 24
d. x - 8 ≤ 21
2. When you look at a graph of the solution of an
inequality, what does a solid dot on the number line mean ? What does an open dot on the number line mean?
3. Tell whether - 2 is a solution of the inequality.
Explain how you decided.
a. x > - 4
b. x + 4 ≤ 2
c. x - 4 < 2
d. x + 3 ≥ 0
4. What strategy do you use to help you remember the
meaning of an inequality symbol when
you are reading?
