Inverse Variation
For any two variables and , the variable varies inversely with if their relationship can be expressed as
The nonzero constant is called the constant of variation. In an inverse variation, as one variable increases the other decreases, and vice versa. The term "inverse" refers to the multiplicative inverse (reciprocal): since the multiplicative inverse of is , the inverse variation formula can be understood as equaling a constant times the reciprocal of . This stands in contrast to direct variation, where and both variables increase or decrease together.
