Opposites & Absolute Value
Which value is greater?
-2 or -1?
-1! It has more value than -2 because it is closer to 0 on the number line. It's only 1 unit away!

A. Opposite of 4
B. |-4| =
A. Opposite of 4 = -4

Quadrant III
What is Absolute Value?
The distance a number is form zero (on a number line) ALWAYS POSITIVE!
A. -2/5
B. 0
C. 200
D. -5
A. -2/5 is a RATIONAL NUMBER
Which point represents the value of | -18 | ?
18
List the following in order from greatest to least. Explain how you know.
{-32, -54, -80, -26, -25}
{-25, -26, -32, -54, -80}
Explain: When ordering from greatest to least, the least negative value has the most value. The farther you move to the left, the value decreases!
In which quadrant is point B located?
Point B (-6, 6)
Quadrant II
True/False
-9 is a whole number?
False
Whole numbers are positive

Define absolute value. Provide one example.
Absolute value is ALWAYS POSITIVE! It's a number's DISTANCE from zero
