The plot of "v" versus above is not linear; although initially linear at low [S, it bends over to saturate at high . Before the modern era of nonlinear curve-fitting on computers, this nonlinearity could make it difficult to estimate "K"M and "V"max accurately. Therefore, several researchers developed linearisations of the Michaelis–Menten equation, such as the Lineweaver–Burk plot, the Eadie–Hofstee diagram and the Hanes–Woolf plot. All of these linear representations can be useful for visualising data, but none should be used to determine kinetic parameters, as computer software is readily available that allows for more accurate determination by nonlinear regression methods.
