A relationship in which one variable increases and the other variable decreases is
called?

Indirect relationship

Explanation:

Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant is indirect relationship Eg:

Where k is the constant of variation. For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5(2) = 10. ... Thus, the equation describing this indirect relationship is xy = 10 .
