Constant of Variatio. 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.

Subsequently, is an inverse relationship direct or indirect?

In short, direct relationships increase or decrease together, but inverse relationships move in opposite directions. Moreover, how do you show inverse relationships?

What is an example of a positive and negative correlation?
