2.A. Secant Lines and Tangent Lines

Secant lines are lines that are based off of two points on a function. Finding the slope of a secant line can be found using the slope equation:      Tangent lines are lines that are based off of one point on a function. Finding the slope of a tangent line can be found using the derivative equation:      Alternative derivative equation:      Key Terms secant line tangent line derivative Essential Questions How is the slope of a tangent line calculated?
