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.

What is direct variation and how would solve direct variations?
k=0.3 and x=65
Can The graphs of two different direct variations can be parallel?
No, the graphs of two different direct variations cannot be parallel. Direct variation is represented by the equation ( y = kx ), where ( k ) is the constant of variation. For two direct variations to be parallel, they would need to have the same slope, which means they would have the same value of ( k ). However, since the variations are different, they must have different values of ( k ), resulting in non-parallel graphs.
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.
Are all direct variations linear functions?
Yes, all direct variations are linear functions. Direct variation describes a relationship where one variable is a constant multiple of another, typically expressed in the form (y = kx), where (k) is a non-zero constant. This equation represents a straight line through the origin on a graph, confirming that direct variations are indeed linear 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.
