If the two variables in direct variation are X and Y then K is Y/X and this gives the equation Y = KX
Equivalently, if you write C = 1/K, then the constant of variation can be calculated as X/Y and this gives the equation as X = CY.
It does not matter which of the two you do as long as you use the correct resulting equation. Because of the relationship between K and C, one of them (at least in terms of school maths) will usually be an integer and so easier to work with.

How are direct variation and joint variation related?
Both are variations of certain kinds of equations. X=kY is a direct variation since X varies directly as Y and k is the constant of variation. X=k/Y is an inverse variation where X varies inversly as Y and k is the constant of variation. Both of these variations are also functions.

What is a direct variation?
A direct variation is when the value of K in multiple proportions is all divisible by the same number for example: XY=(1)(10) K=10 XY=(2)(20) K=40 XY=(3)(30) K=90 XY=(4)(40) K=160 In this situation the constant (K) of each proportion is divisible by 10 making the multiple equations a direct variation.
