Subject: Hyperbola
I have been teaching my Algebra 3/4 students conic section equation writing by

starting with a graph and then finding the focus (or foci) and then using the

definition to write the equation of the circle, ellipse, parabola, or

hyperbola. My Question:

I was delighted to work out how to find the focus of the parabola by

construction, but am a little stumped by how to find the asymptotes of the

hyperbola (without advance knowledge of the equation, and other than simply

"eyeballing" the asymptote).

Is it possible? Or does someone out there have a better way?

Thanks!
