Direct variation is the formula y = kx and Indirect is y = k/x ... Example: The Volume of the oil in the barrel varies directly as the Temperature. If V = 27 when T=3, then find the constant of variation (or constant of proportionality).-----

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.
DIRECT AND INVERSE VARIATION WORKSHEET
Once the variation constant is known, the value of either the dependent variable or the independent variable can be found if the other is known: x = k/y or y = k/x. Putting “Inverse Variation” in Applicable terms: Inverse variation is applicable in many disciplines. For instance a lever is an example of inverse variation.

The relationship above is an example of _____ Another way to say this is _____ In general: Direct Variation: Direct variation occurs when the . ratio. of the variables does not change. Or in other words, when the dependent variable is a . constant multiple. of the independent variable. Direct variation can be defined algebraically as or ...
