Learn all about points lines and planes. So here K will be 10. An incomplete quadratic equation is of the form ax 2 + bx + c = 0, and Since this is inverse variation, we have to apply the shortcut straight multiplication. The value k is a nonzero constant greater than zero and is called the constant of variation.

We can also express the relationship between x and y as: y = kx. A = r2 In the language of variation, this equation means: the area A varies directly with the square of the radius r .and the constant of variation is k = . The equation that represents a proportional relationship, or a line, is y=kx, where k is the constant of proportionality. The equation for a direct variation function line is always of the form y = m*x for some constant m We are told that (x,y) = (6,2) is on the. The statement " y varies directly as x ," means that when x increases, y increases by the same factor.
