<p>In other words, F is proportional to the logarithm of x times the slope of the straight line of its lin-log graph, plus a constant. Specifically, a straight line on a lin-log plot containing points (F<sub>0</sub>,&nbsp;x<sub>0</sub>) and (F<sub>1</sub>,&nbsp;x<sub>1</sub>) will have the function:</p>
