Question

Find the constant of variation k for the direct variation. 4x = -y

Answer 1

k = - 4

Explanation:

The equation representing direct variation is

y = kx ← k is the constant of variation

Given

4x = - y ( multiply both sides by - 1 )

- 4x = y , that is

y = - 4x ← in standard form

with k = - 4
