variation equation calculator, direct variation, inverse variation. Member Log In. Variation Equations Calculator The slope of this line is the constant of variation. In other words, in the equation \(y mx\), m is the constant of variation. Example A: If y varies directly as x, and \(y 8\) when \(x 12\), find k and write an equation that expresses this variation.
Plan of Attack: Plug the given values into the equation \(y kx\). Solve for k. The formula for direct variation is, where is the constant of variation. Solve the equation for, the constant of variation. Replace the variables and with the actual values.

Direct Variation. Direct variation is a relationship between two variables that describes how the two variables relate to one another. This type of variation can be represented using a direct variation equation. This expression will go on the bottom of the fraction, and the variation constant k will go on top, so my equation so far is: y k ( w x ) 2 In order to find the complete equation for y, I'll need to find the value of the constant.
