Slope of Tangent Line Derivative at a Point Calculus 1 AB

I explain how to find the instantaneous slope at a given point along a curve. I finish by finding the tangent line to that curve at that point. All three of the examples I work in this video have real values of slope and thus have a real limit as h approaches 0. I do examples that have vertical tangent lines at the point of tangency and thus an undefined slope in a later video.
