I solve temp change like this(an am correct):
You remove the minus from the negative number and add both numbers and you have your answer.
56+44=100
Your answer is:100 degrees Fahrenheit.

Question 2.
(1,0) would go (-1,0)
(3,0) would go (-3,0)
(5,3) would go (-5,3)
(1,3) would go (-1,3)
question 4. (i think)
(0,-1) would go (-1,0)
(0,-2) would go (-2,0)
(-2,-2) would go (-2,2)
(2,0) would go (0,2)
question 5.
(-1,4) would go to (1,4)
(-1,2) would go to (1,2)
(-3,2) would go to (3,2)
(-4,4) would go to (4,4)
hope this helps! good luck!
