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 …

direct variation. indicates a relationship between x and y, where the same number is multiplied times each x value in order to get the y value. In direct variation, the ratio of change between the x values and the y-value is always the same. Direct variation can be identified using the equation y = kx, where k is the constant, or the number multiplied times x to find y. K is similar to m (slope) in y=mx+b …

direct variation. It is said that one variable "varies directly" as the other. The constant ratio is called the constant of variation. The formula for direct variation is . y = kx, where k is called the . constant of variation. In a direct variation, the two variables change in the same sense. If …

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 go . down.
DIRECT AND INVERSE VARIATION WORKSHEET
Direct Variation. When two variables, x & y vary directly, then . y = k(x . where . k is a constant. called the "constant of proportionality." When there is direct variation between variables x and y, doubling the value of x will always result in y being doubled. Also, if x is cut in half, then y is cut in half.
