Direct

This equation is of the form $y = k x$ $y=kx$ , where $k = \frac{1}{10}$ $k=1/10$ . Therefore, this is an example of direct variation.

$y = \frac{x}{10}$ $y=x/10$ is a direct variation, because everything you do to $y$ $y$ will result in a similar change in $x$ $x$ .

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

For: $y = \frac{x}{10}$ $y=x/10$ , if you multiply both sides by $3$ $3$ , or triple the equation,

$3 y = 3 (\frac{x}{10}) = \frac{3 x}{10}$ $3y=3(x/10)=(3x)/10$

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

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