Y is equal to negative 3X, (I'm saving this real state for inverse variation in a second) you could writethis or you could algebraically manipulate it you could maybe divide both sides of this equation by X and then you will get Y/X is equal to -3 or maybe you divide both sides by X and then you divide both sides by Y so from this you would get, so if you divide both sides by Y now you could get 1/X is equal to negative 3 times 1/Y these three statements, these three equations are all the same thing so sometimes the direct variation isn't quite in your face but if you do this, what I did right here with any of these you would get the exact same result or you could jus try to manipulate it back, to this form over here and there's other ways we could do it we could divide both sides of this equation by negative 3 and then you would get negative 1/3Y is equal to X and this is kind of an interesting case here because here this is X varies directly with Y or we could say X is equal to some K times Y and in general that's true if Y varies directly with X, though we can also say that X varies directly with Y it's not going to be the same constant, it's going to be essentially the inverse of that constant but they're still directly varying now with that said so about direct variation
