You're on a roll — The Lineweaver-Burk equation is a rearrangement of the Michaelis-Menten equation, which linearizes the relationship between reaction velocity and substrate concentration. This linear form makes it easier to determine Vmax and Km graphically.
The equation is:
$$ \frac{1}{v_0} = \frac{K_m}{V_{max}} \cdot \frac{1}{[S]} + \frac{1}{V_{max}} $$
Where:
$v_0$ is the initial reaction velocity.
$K_m$ is the Michaelis constant.
$V_{max}$ is the maximum reaction velocity.
$[S]$ is the substrate concentration.
When $1/v_0$ is plotted against $1/[S]$ (a Lineweaver-Burk plot or double reciprocal plot), it yields a straight line.
The y-intercept* is $1/V_{max}$.
The x-intercept* is $-1/K_m$.
The slope* of the line is $K_m/V_{max}$.
