In this video the instructor shows how to find the slope of a line given two points that like on the line. Slope of a line is the measure of the steepness of the line compared to the angle made by the line with the x-axes. Do you understand the function of slope, how to find it given two points, and what it tells us about a line? The purpose of this exercise is to approximate the tangent slope of a curve. If you draw it out, I think you will understand. Sketch the curve and the secants if they give you something like find the slope of the secant line joining(1, f(1)) and (8, f(8) and it says let f(x)x2-5x how would youSecent line is one that connects two points of the function curve, while the tangent would be tangent to it at the point (there would be only one point given in that case).
