Direct linear plot
In biochemistry, the direct linear plot is a graphical method for enzyme kinetics data following the Michaelis–Menten equation. In this plot, observations are not plotted as points, but as lines in parameter space with axes K m {\displaystyle K_{\mathrm {m} }} and V {\displaystyle V} , such that each observation of a rate v i {\displaystyle v_{i}} at substrate concentration a i {\displaystyle a_{i}} is represented by a straight line with intercept − a i {\displaystyle -a_{i}} on the K m {\displaystyle K_{\mathrm {m} }} axis and v i {\displaystyle v_{i}} on the V {\displaystyle V} axis.
