you can get the constant variation by dividing the Y coordinate to the X coordinate.
there is 1 constant variation in every set of X and Y.
(3,30)=10
(9,10)=1.111...
(15,6)=0.4
I believe you need to find the constant variation from the set of X and Y, and see if there are any match to the given option
