So it would be very nice if we could somehow represent vapor pressure and temperature in an easier relation, in an easier function. And mathematically, one of the most simplest functions is a linear function. And a linear function is represented by this equation y equals MX plus B, where y is our range value, x is our domain value, m is a constant slope, and B is the y intercept. Now, this is exactly what the closest Clayton relation does. These were two scientists who developed mathematically and the experimental result, this relationship where this is our y value, this is our slope, this is our X value, and this is our Y intercept. This is the natural log of vapor pressure of our liquid.
