*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. - Two variables
*x*and*y*will be in inverse propor…
