Direct variation is the formula y = kx and Indirect is y = k/x So basically if something varies directly (or jointly) it will be multiplied by the k, if it varies indirectly or inversely, k will be divided by it.

I. Direct Variation: y varies directly as x or y is directly proportional to x (y = kx) where k is the constant of proportionality or constant of variation. As x gets larger, y gets larger or as x gets smaller, y gets smaller. A line with a y-intercept of 0 is a …

Direct, Inverse, Joint and Combined Variation – She Loves Math
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.

Variation, in general, will concern two variables, say height and . weight of a person, and how when one of these changes, the other might . be expected to change. We have . direct variation. if the two variables . change in the same sense, i.e. if one increases, so does the other. We have indirect variation if one going up causes the other to ...
