Direct Variation

A linear relationship between two variables, x and y, that can be written in the form y=kx, where k is a nonzero constant constant.

Constant of Variation

The constant k in direct and inverse variation equations.

Ordered Pair

Proportional Relationship

A relationship between two quantities in which of the ratio of one quantity to the other quantity is constant.

Rate of Change
