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 if x/y=k= [k is a positive number] = Constant

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, if xy = k= Constant
