Question

Which equations show direct variation between u and v?

Choose all answers that are correct

A: v = 1/u + 6

B: v/u = 9

C: 0.5(1/u) = v

D: 3.5u = v

Answer 1

Direct variation is represented by:

y = kx

or:

v = ku

Where 'k' is constant and can be any number..so which one do you think? @TFIOS_GUS623

Answer 2

I honestly don't know, sorry

Answer 3

Well, which one looks like it's in: v = (?)u
^ This can be any number

Answer 4

Well, you have to participate if you want to get the answer..

Answer 5

I don't know, maybe A?

Answer 6

No, I don't think that's right..

v = ku

Or it could be switched around like:

ku = v
