Start at (-3,5)

Reflect over the x-axis

(-3,-5)

Why is -10.9 degrees Fahrenheit colder than -5 degrees Fahrenheit. Justify using INEQUALITY STATEMENTS
-10.9 is colder than -5 because -10.9<-5

If a point is plotted on (-3,-2), what are the coordinates of the point that is 5 spaces away and in Quadrant IV?
(2,-2)
200

When you reflect (8,-1) over the 

y-axis, you will get these coordinates

(-8,-1)

200
The integer you would use to represent losing 25 yards for a penalty in football.
-25

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

200
The prairie dogs have a nest with the entrance at the location (1,4). The other entrances are 5 feet away. What are the coordinates of the possible entrances?
(6,4) and (-4,4) and (1,-1) and (1,9)
300
Start at (7,3) and reflect over the x-axis
(7,-3)
300
The rational number for spending $4.30 on a bag of chips
-4.30
300

If a house is at the coordinates (8,0) and the park is 3 miles away. A possible location for the park is (8,3) and (8,-3)

True, away could mean up or down so both would work.

300
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
400
If you reflect (-3,-3) over the y-axis, you will end up here
(3,-3)
400
Joe found the opposite of -4 and then found the opposite of that number. What number does he have now?
-4
400
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
400
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
400
A point is plotted at (4,-7) If this point is reflected over one axis, where would it land?
either (-4,-7) or (4,7)
500
Plot all possible reflections over one axis for the point (4,-2)
(4,2) (-4,-2)
500
Write the rational number for each action: Finding $20, Giving $4 away, Earning $10, Buying a $15 toy
20 -4 10 -15
500
The distance from point (8,-2) to point (-2,-2) is 10 spaces
True because |8|+|-2| = 10 segments
500

c) The absolute value of 7

a: yes, the opposite of the opposite of 7 is 7 

b: no, the opposite of 7 is -7

c: yes, the absolute value of 7 is 7
