So back in the day before computers, we really had no way of using this graph to actually calculate what v max and Km is. So back in the day, instead of using this Mikhailis Methane equation in this form, we changed the equation into a slightly different form. And what we did was we took the reciprocal of the left side and the right side of that equation. Now remember, in mathematics, if we have an algebraic equation and we change the right side and the left side in the same exact way, that does not actually change the information that the equation provides us with. It doesn't change the information. But what it does is it changes the way that that information is actually displayed.
