Answer:

A

Step-by-step explanation:

The standard equation of proportion is

y = kx ← k is the constant of proportionality

A

y = 5x is in this form with k = 5

B

y = [tex]\frac{10}{5}[/tex] x = 2x with k = 2 ≠ 5

C

y = [tex]\frac{5}{25}[/tex] x = [tex]\frac{1}{5}[/tex] x with k = [tex]\frac{1}{5}[/tex] ≠ 5

D

y = [tex]\frac{1}{2}[/tex] x with k = [tex]\frac{1}{2}[/tex] ≠ 5
