In this lesson I start by setting up the example with you. Then at 15:08 I show you how to find the Point of Tangency when given the equation of the tangent line and a circle. In the first solution I work through the slope formula using the fact that the tangent line and radius are perpendicular. The second method starting at 26:00 I just use straight substitution to solve the system of equations between the tangent line and the circle.
