Bill, I got an off-list mail from another list member and I'll quote his 
mail rather than answer it myself. I'm sure he won't mind my quoting him 
anonymously.

I see by Bill Robertson's most recent post that he doesn't understand 
your previous message.  Good times :-)

"

Go back and re-read my message(s), Bill. I am very careful when writing 
them to avoid ambiguity and be precise in what I'm saying.

Answer me one question - do you understand what I mean by a straight 
line graph being described by the generic equation y=Mx+C ?
