answer:

In direct variation, as one number increases, so does the other. This is also called direct proportion: they're the same thing. ... In inverse variation, it's exactly the opposite: as one number increases, the other decreases. This is also called inverse proportion.

Direct Variation - if a number increases the other number also increases

Equation: y = kx

Indirect Variation - when one of the variables increases, the other one decreases

Equation: y=k/x

Joint Variation - more than two variables are related directly

Equation: y=kxz

In direct variation, as one number increases, so does the other. This is also called direct proportion: they're the same thing. An example of this is relationship between age and height. In inverse variation, it's exactly the opposite: as one number increases, the other decreases.
