(D) In part (C), we saw that the limit of the slopes of the secant lines through the point (1, f(1)) is 2. If we graph the line through (1, f(1)) with slope 2, then this line is the limit of the secant lines. The slope obtained from the limit of slopes of secant lines is called the slope of the graph at x = 1. The line through the point (1, f(1)) with this slope is called the tangent line.
