Direct and Indirect Variation. Indirect Variation. We gave an example of inverse proportion above, namely speed and time for a particular journey. In this case, if you double the speed, you halve the time. So the product, speed x time = constant. In general, if x and y are inversely proportional, then the product xy will be constant.

There are two types of variation, direct and inverse. Two variables are in direct variation if one is a constant multiple of the other. This can be represented by the equation 𝑦=𝑘𝑥, where 𝑘 is the constant of variation (or proportionality). ... graphing calculator to show how the graphs change as the degree of a polynomial changes.
