100 POINTS!! and brainiest! Which of these sets of coordinates are proportional?
A. (3, 1), (6, 2), (9, 3)
B. (2, 4), (4, 6), (7, 9)
C. (1.5, 3), (3, 6), (4, 8)
D. (3, 1), (4, 3), (8, 6)

Divide x by Y for each set if they all have the same value they are proportional:

A: 3/1 = 3, 6/2 = 3, 9/3 = 3 This is proportional.

B: 2/4 = 1/2, 4/6 = 2/3, 7/9 = 7/9, Not proportional.

C: 1.5/3 = 1/2, 3/6 = 1/2, 4/8 = 1/2 This is proportional.

D: 3/1 = 3, 4/3 = 1 1/3, 8/6 = 1 1/3, Not proportional.

The answers are A and C are proportional.

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

they would have to work 32 hours.
