I was wondering if anyone could help me with this problem(adsbygoogle = window.adsbygoogle || []).push({});

A circle is tanget to line 2x-y+1=0, at point (2, 5), and the center point is on line, x+y=9. Determine the equation (in general form) of the circle.

Normally I can do this sort of problem but I am having a hard time with this one. I don't know how to determine the center point or radius.....frustrating..

Thanks, Jennifer
