I'm not sure if the following is possible or whether it exists somewhere between the realms of fantasy and science fiction. I have been unable to do it. Given a list, set, vector (whatever you want to call it) consisting of functions of the same variable, i.e. list = {a1+b1*k, a2+b2*k, a3+b3*k...} Assuming they are all linear (of the form a+b*k) is there away to isolate the a_i and b_i values? Essentially I would like to get a list "A" consisting of all the intercept values, and a list "B" consisting of all the slope values. Is this possible? What kind of operations do I need to use to accomplish this (if indeed it is possible)? Thanks for any insights.
