Remember, in the presence of a competitive inhibitor, the affinity of that substrate for the active side decreases. And so we have to increase the concentration of S to basically get all those active sites occupied with that substrate. And so Km will actually increase. Now, if Km increases, then because the slope of the line is Km divided by VMAX, VMAX will not change, km increases. And so the ratio Km divided by VMAX also increases. And that's precisely why the slope of the purple one purple line is greater than the slope of that red line.
