So the x coordinate is one divided by the concentration of S. The slope of the straight line is Km divided by v max. So the slope of the red line is km divided by v max, and the y intercept is one divided by v max. So what this really tells us is the point where the curve intersects the y axis is the quantity one divided by v max. So if we carry out our experiment, we collect the data points and then we plot the double Reciprocal curve. If we find what this y value is, so let's say it's 20, then we know that is equal to one divided by v max. And if we solve for v max, we get that v max is equal to 0.5.
