The point (-3,-4) is 10 spaces away from (-3,6)
True
|-4| + |6| = 10 spaces

The original cost of a lamp is changed by -$5.50
James said the cost decreased by |-$5.50|. Is he correct?
He is correct because |-5.50| is 5.50 and decreased is a negative key word

-4.30
300
If a house is at the coordinates (8,0) and the park is 3 miles away, a possible location for the house is (8,3) and (8,-3)
True, away could mean up or down so both would work

Start with $20 in the bank. By the end of the week, the ending balance has an absolute value of $40. Did you gain or lose money?
It could be both because |40|= 40 and |-40|=40 so the amount could be $40 or -$40 so it could have gone up or down
300
How many spaces are between the points (-3,2) and (7,2)?
What equation can show this (using absolute value)?
10 spaces with the equation l-3l + l7l

The point (-5,3) is in Quadrant IV
False a negative and then a positive will land in Quadrant II
positive then negative lands in Quadrant IV

The temperature in the morning was -3 degrees. Tomorrow the temperature is supposed to have an absolute value of 6 degrees. Will the temperature go up or down?
It could be either because both -6 degrees and 6 degrees are 6 spaces away from zero.
-3 > -6 and -3 < 6
