Question

What is the constant of variation for the relationship f(x)=30x? A.10 B.30 C.x D.f(x)

Answer 1

In a linear relationship looking like y = k x, it's k that is the constant of variation, or proportionality constant.

Answer 2

I'm still confused tho how would I solve that?

Answer 3

You don't need to "solve" this problem. You're supposed to IDENTIFY the constant of variation. Have you tried looking up "direct variation" or "direct proportion" on the 'Net? You'd get your answer almost immediately if you'd do that.
