Direct

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

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

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.

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.
