In this lesson, you will learn about tangent lines to curves and how to estimate their slope. A tangent line is a line that touches the graph in one point and is going in the same direction as the graph at that point. By estimating the slope of the tangent line, you can learn how to find the equation of the tangent line. You will learn the point-slope formula and the slope-intercept form to find the equation of a tangent line.
