Answer: -23
Step-by-step explanation:
The change in y value can be determined by subtracting the first value from the second.
-19 - 4 = -23
Or if you think about it logically you are going from a positive number to a negative so the total distance will be greater than both of your values.

Answer:
13) 25 and 17
14) cupcakes = $5
brownies = $3
Step-by-step explanation:
13)  you can set this up as equations
so x + y = 42
x-y = 8
solve simultaneously by subtracting from each other
2y = 34
y= 17
if y = 17
42 - 17 = 25 = x
14) set up as equations again
Ben    7c + 10b = 65
franklin   7c +7b = 56
subtract from eachother
3b = 9
b = $3
7c + 10(3) = 65
7c = 35
c = $5
