Question

Solve the equation for the y-value and choose whether it is a direct variation or inverse variation.

3y = x
A. inverse variation
B. direct variation

Answer 1

B

Explanation:

the equation representing direct variation is

y = kx ← k is the constant of variation

The equation representing inverse variation is

y =
`(k)/(x)` ← k is the constant of variation

Given

3y = x ( divide both sides by 3 )

y =
`(1)/(3)` x ← equation representing direct variation

with k =
`(1)/(3)`
