Title: General Form for Linear Equations on CAS (TI-89 Titanium)?
Post by: redgreenblue on October 24, 2011, 06:17:18 pm

In multiple choice, often there is a question involving hyperbolas and finding the equations of the asymptotes, given in a general form without y as the subject, i.e.

and

Might be an option in the multiple choice exam.

On the calculator is there a function one can execute with the parameters being an equation of the form y=x and have the calculator rearrange the expression to the general form y-x=0? The algebraic manipulation is something I'd like to be avoiding if I can get a CAS method to perform the routine for me.

Thanks in advance.

Edit: Messed up copying out the equation, fixed.
