If you have already determined whether your particular model is direct or inverse variation, then the two models will follow the following functions:

Direct: y=kx

---y is always expressible as a constant multiple of x, meaning it varies directly with x by a factor of k

Inverse: y=k/x

---y is always expressible as a constant multiple of the inverse of x (1/x). It varies directly with the inverse of x by a factor of k.

B. Constant

variation

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.

No, this is an inverse variation.

The additive inverse is used to solve equations; equations, in turn, are used to model many real-world situations.

it would be, X*Y=K (X multiplied by Y equals K) You get inverse equations when there is no specific number you are multiplying by. it can also be Y=K/X, hope this helps :)

The inverse variation is the indirect relationship between two variables. The form of the inverse variation is xy = k where k is any real constant.

If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).

Inverse variation does not pass through the origin, however direct variation always passes through the origin.

Direct variation is the ratio of two variable is constant. Inverse variation is when the product of two variable is constant. For example, direct variation is y = kx and indirect variation would be y = k/x .

No, this is an inverse variation.
