Answer:
5.5
Step-by-step explanation:
The rate of change is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (16.5 -11)/(3 -2) = 5.5/1
m = 5.5
The rate of change of this function is 5.5.
Proportional:
4/7 and 10/17.5
2/3 and 9/12
18/8 and 9/4
NOT proportional:

7/5 and 27/50
I got All Real Numbers (infinite answers); what's your answer choices?
Subtracting a negative number is the same as adding a positive number
assume your number is n
n - (-10) = 6
n + 10 = 6
subtract 10 from both sides
