Question 1052958: A theorem from geometry states that a line passing through the center of a circle and through a point P on the circle is perpendicular to the tangent line at P. (See the figure.)
(a) If the coordinates of P are (3, 6) and the coordinates of c are (2, 5), what is the equation of the tangent line?
(b) What are the intercepts of the tangent line?
