Question

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

-4x + y = 0

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

- 4x + y = 0 ( add 4x to both sides )

y = 4x ← equation representing direct variation

with k = 4
