Two quantities, x and y, are said to be in direct proportion, if they increase (decrease) together in such a manner that the ratio of their corresponding values remains constant. That is x/y = k, where k is a positive number.
 
Two quantities, x and y, are said to be in inverse proportion, if an increase in x causes a proportional decrease in y (and vice-versa) in such a manner that the product of their corresponding values remains constant. That is, xy = k, where k is a positive number.
