Question

Write an appropriate direct variation equation if y=27 when x=9

Answer 1

We just went over these :D

When doing direct variation y / x = k

SO, 27 divided by 9 is 3.

k = 3

Inverse Variation is you want to multiply to find each one ( xy = k )

Answer 2

so the answer would only be k=3??

Answer 3

No, it'd be 27 / 9 = 3

using the y / x = k.

Answer 4

Sorry.
