**Offline Version**: PDF

**Term inverse Definition**: The mathematical notion that two variables change in the opposite directions, that is, an increase in X goes with a decrease in Y, or a decrease in X goes with an increase in Y. The alternative to an inverse relation is a direct relation, in which an increase in one variable goes with an increase in the other. Inverse relations are graphically illustrated by negatively-sloped curves, a common example being the demand curve.
