Transport of pilocarpine across the corneal membrane

I am trying to work through calculations to obtain the delta H and delta S in the example 3 - 14 on page 71 of Martin's Physical Pharmacy. A set of data (log Ka v. 1/T x 10^3) is plotted and the linear form of the van't hoff equation should be used to calculate delta H and delta S. The equation in this form is:
ln K = -(delta H/R)1/T + delta S/R or y = mx + b where : delta H/R = m and delta S/R = b.

In the study of the transport of pilocarpine across the corneal membrane of the eye, Mitra and Mikkelson presented a van't Hoff
