Question

Is `y=x/10` a direct of inverse variation?

Answer 1

Direct

Explanation:

This equation is of the form `y=kx`, where `k=1/10`. Therefore, this is an example of direct variation.

Answer 2

`y=x/10` is a direct variation, because everything you do to `y` will result in a similar change in `x`.

Explanation:

As you know, it is often necessary to multiply or divide variables to add or subtract them.

For: `y=x/10`, if you multiply both sides by `3`, or triple the equation,

`3y=3(x/10)=(3x)/10`

You can try any multiple or division of the equation, and `x` will always vary as does `y`, and vice-versa.

That is because `y` and `x` are in a direct variation.
