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