let's explore inverse variation inverse variation the general form (if we use the same variables) it always doesn't have to be Y and X, it could be A and a B it could be a M and an N now to inverse varitaion, so if I did it with Ys and Xs this would be Y is equal to some constant (K) times 1/X so instead of being some constant times X, it's some constant times 1/X so let me show you a bunch of examples it could be Y is equal to 1/X it could be Y is equal to 2 times 1/X which is clearly the same thing as 2/X it could be Y is equal to 1/3 times 1/X whis is the same thing as 1/3X it could be Y is equal to -2/X and let's explore this, the inverse variation the same way we explain the direct variation so let's pick Y is equal to 2/X and let me do that same table over here if X is 1, then Y is 2 if X is 2 then 2 divided by 2 is 1 so if you multiply X by 2 you scale it up by a factor of 2, what happens to Y?
