Is #y/x = 4/3# a direct variation equation and if so what is the constant?

Answer 1

Eva Abramson

The constant is #4/3#.

In a direct variation equation #y# is proportional to #x# i.e. #ypropx# i.e. #y=k×x#, where #k# is constant.

In other words #k =y/x#

As we have #y/x=4/3#,

The constant is #4/3#.

Yes, (y/x = 4/3) is a direct variation equation. The constant of variation, (k), is the ratio of (y) to (x) when both are not zero. In this case, the constant of variation is (k = 4/3).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
