We can calculate the slope of a tangent line using the definition of the derivative of a function f at x = c (provided that limit exists): lim h → 0 f (c + h) − f (c) h. Once we've got the slope, we can find the equation of the line. This article walks through three examples.
Practice drawing the graph of a line given in slope-intercept form. For example, graph y = 3x + 2.
