Constant of Variation -
The ratio between two variables in a direct variation or the product of two variables in an inverse variation. In the direct variation equations
= k
and
y = kx
, and the inverse variation equations
xy = k
and
y = 
,
k
is the constant of variation.

Direct Variation -
A statement of the form
= k
or
y = kx
, where
k
is a constant of variation.
