Answer:

#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.
