If you triple x, you're also gonna end up tripling y. Inverse variation. You have y being equal to some constant times one over x. So instead of an x here you have a one over x or if you multiply both sides by x you get x times y is equal to some constant. And you could switch the x's and the y's around as well for inverse variation.

Inverse Variation For an inverse variation, k is still the constant of variation, but the model differs from direct variation. The variables x and y vary inversely for a constant k. Example When x is 7 and y is 2, find an equation that inversely relates y and x. Solution The inverse variation that relates x and y is Graphically it looks like this:

Inverse variation formula exists between any two variables when one quantity is inversely dependent on the other i.e., if one quantity increases, the other quantity decreases, and vice versa. Since the two variables are inversely related to each other it …

An inverse variation can be represented by the equation x y = k or y = k x . That is, y varies inversely as x if there is some nonzero constant k such that, x y = k or y = k x where x ≠ 0, y ≠ 0 . Suppose y varies inversely as x such that x y = 3 or y = 3 x . That graph of this equation shown.

y = (1/k) x OR y = x/k. where, k is the constant of proportionality. Let's say y1 y 1 inversely varies with x1 x 1 and y2 y 2 inversely varies with x2 x 2 then, the inverse variation formula is given by. x1y1 = x2y2 x 1 y 1 = x 2 y 2. Below is the graph is shown for the inverse variation relationship between x and y.
