**1. Homework Statement**

(Data fittings)

for y = D/(x+C)

my book do:

y = (-1/C) *(xy) + (D/C)

I do:

1/y = (1/D)*x + C/D

so using y=Y and X = xy

book finds A and B in Ax+b =y

so, finds an equation that fits the data

It hints that my way is absurd. I really couldn't get what's wrong with using 1/y = ..
