Best Answer

Consider two variables x and y.

If x varies directly as y then y = cx where c is some constant of variation. This means that whenever x increases, y increases and it increases by c times as much as the increase in x. Also, if x decreases, then y decreases by c times the decrease in x.

If x varies inversely as y then y = k/x where k is some constant of variation. This means that whenever x increases, y decreases and it decreases by k times as much as the increase in x. Also, if x decreases, then y increases by k times the decrease in x.

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.

For example the number 5. * A direct proportion would be 5/1 * The inverse would be 1/5

First determine whether the equation is a direct variation or a regular equation. 1. Direct Variations in inverse can be solved in the following. y=6x switch y with x ---> x=6y solve for y 2.Regular equations in inverse can be solved in the following. y=-2x-10 switch y with x----> x=-2y-10 add 10---> x+10=2y solve for y
