I can do everything, untill it gets to the point of actually putting the system into an eigenvector form, then im stuck. I won't put the actual numbers down, but say I have a system of equations like:

ax = by

How do I put this into eigenvector form?

Is it simply (a,b) or is it (1, b/a) or what?

I don't know what to do.

Thank you :)
