Negative bc negative times positive is negative
Divide each set to see if the answers are identical:
A: 3/2 = 1.5
6/3 = 3
Answers are not the same so this is not proportional.
B: 20/4 = 5
24 /6 = 4
Answers are not the same so this is not proportional.
C: 27/9 = 3
81/27 = 3
Answers are the same so this is proportional.
D: 8/2 = 4
16/8 = 2
Answers are not the same so this is not proportional.
The answer is C.
27 - 2m when m = 3 is 27 - 2(3) = 27 - 6 = 21
