Hi Melody,
Thank you for answering. The question is about a parabola and straight line intercepting on a plane, and all the normal questions one can expect to find, is asked. Then the one I asked about. I was thinking that, to make a drawing of this whole thing just for a 4 point question I do not understand, is way not worth the effort. So, I think I'm going to sit this one out. Anyways, as usual, thank you very much for being out there!!!!..I do appreciate!
