i am more concerned with how this is supposed to be done than the actual answer
a line crosses through the point (5, -2)
there is a circle x^2 + y^2 = 9
at what point(s) is the line tangent to the circle?
i realize the slope of the line is perpendicular to the slope of the radius, but that's not helping me get very far
