I'm not sure I understand the problem properly but couldn't you put
something like this at the end of your program:

Disp SLOPE >Frac
Disp ICEPT >Frac

Where ">Frac" obtained by pressing 2nd+Math, Misc, More, F1.
(Incidentally this is the most usefull thing to have on your custom
menu).  If you want the variable to look like fractions then you have
to press ">Frac" each time, the calculator stores all numbers the same
way and as far as it is concerned all numbers are rational.  Also if
the numbers cannot be easilly turned into a fraction (the denominator
must have 4 digits or less) then the calculator can't turn it into a
fraction.

If this doesn't help then explain the problem to me in more detail and
I'll have another look at it.
