WebThis is direct variation because one variable, y, varies directly with the other variable, x, which is scaled by a constant, k. y=k*1/x is the only form of inverse variation, although it can look quite different when you apply some algebraic manipulation. For instance, y=k*1/x is the exact same thing as y=k/x, or xy=k. WebDirect variation occurs when an increase in one variable is results with an increase in value of the other variable.
