What about the Km? Well, notice that the red curve also touches intersects the x axis. And if we basically let the left side of the equation equal to zero, we can solve for what the x axis is. The x axis is equal to negative of one divided by Km. And so if we find exactly what the x value is, again, let's suppose, I don't know, it's negative two. Then we set negative two equal to negative one over Km, and we find that Km is equal to zero five.
