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. WebTwo variables, x and y, are called directly proportional if an increase in x or y causes a corresponding increase in the other variable, i.e. y or x, or a decrease in one variable results in a reduction of the other variable. In this case, the product of x and y is equal to a constant value. What is an example of an inverse proportion?
