Answer: Direct Variation: quantity y are varies directly as quantity x or y is directly proportional to x,if and if y=kx,whre k is the constant of variation, or constant of proportionality                                                                                                                                                                                                                                              

Inverse Variarion: Two variables are  so related such that as one variable increases,the other variable decreases proportionally .For variables x and y and constant k,if xy is equal to k,then y is inversely proportional to x,or y varies inversely
