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_\mathrm{m} and V , such that each observation of a rate v_i at substrate concentration a_i is represented by a straight line with intercept -a_i on the K_\mathrm{m} axis and v_i on the V axis. Ideally (in the absence of experimental error) the lines intersect at a unique point (\hat{K}_\mathrm{m}, \hat{V}) whose coordinates provide the values of \hat{K}_\mathrm{m} and \hat{V} .
