Answer:
B
Step-by-step explanation:
the equation representing direct variation is
y = kx ← k is the constant of variation
The equation representing inverse variation is
y =
← k is the constant of variation
Given
3y = x ( divide both sides by 3 )
y =
x ← equation representing direct variation
with k =
