Direct Variation and Inverse Variation Worksheets
In inverse variation, if multiply x times y, you will always get the same answer, and therefore our formulas are flipped. Inverse Variation Equations: Inverse Variation: y = k/x. Constant: k = yx. Finding x: x = k/y. You will notice that each of the equations is the exact inverse of the direct variation equations. Inverse Variation looks like ...
