Answer:
Option B is correct. [tex]y=\frac{1}{5} x[/tex]
Step-by-step explanation:
Going by the proportionality's definition:
[tex]y[/tex] is proportional to [tex]x[/tex], if:
[tex]y =kx[/tex]
Therefore, for [tex]k=\frac{1}{5}[/tex],
The equation [tex]y=\frac{1}{5} x[/tex] represents a proportional relationship.
