could be simplified as
According to
http://www.merriam-webster.com/dictionary/direct%20variation
Definition of DIRECT VARIATION
: mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other
from which it follows that the given equation is not a direct variation (i.e.
The equation of a line parallel to this which would be a direct variation would be
or
and for this equation the constant of variation would be
