You will notice that each of the equations is the exact inverse of the direct variation equations. Inverse Variation looks like the below: x 5 10 20 40 80 y 16 8 4 2 1 You will notice that in each case, if you multiply x times y, you will get 80. Now we can plug our numbers into the equations in order to determine the equation.
