The effects of different types of reversible enzyme inhibitors on enzymatic activity can be visualized using graphical representations of the Michaelis–Menten equation, such as Lineweaver–Burk plots, Eadie-Hofstee plots or Hanes-Woolf plots. For example, in the Lineweaver–Burk plots at the right, the competitive inhibition lines intersect on the "y"-axis, illustrating that such inhibitors do not affect "V"max. Similarly, the non-competitive inhibition lines intersect on the "x"-axis, showing these inhibitors do not affect "K"m. However, it can be difficult to estimate "K"i and "K"i' accurately from such plots, so it is advisable to estimate these constants using more reliable nonlinear regression methods, as described above.
