Answer:
A, C, D
Step-by-step explanation:
In a proportional relationship, y = kx, k is the constant of proportionality.
A)
4y = x
y = 1/4 x
k = 1/4 Yes
B)
y = 4x
k = 4 No
C)
32y = 8x
y = 8/32 x
y = 1/4 x
k = 1/4 Yes
D)
y = 0.25x
k = 0.25 = 1/4 Yes
E)
1/4 y = 2x
y = 4 * 2x
y = 8x
k = 8 No
Answer: A, C, D
