Question

Which equations show direct variation between a and b?

Choose all answers that are correct.

A. B=0.7a


B. B=1/8a-3


C. 5 (1/a)=b

Answer 1

For direct variation, the constant a will be multiplied directly. Cases where 1/a is used do not come under it.

I simply mean that b=ax is a direct variation whereas b=(1/a)x is not.
