Inverse Variation 2.5

In direct variation, if one variable increases, so does the other. Inverse variation is the opposite.

Definition Inverse Variation is when one variable increasing causes the other to decrease. Example: Walking speed vs. time to get to school. Walk faster=times decreases Walk slower=time increased.

Recall equation for Direct Variation y=kx

Equation for Inverse Variation

Vocab x and y are inversely proportional, and k is the constant of variation.
