Linear functions are routinely used to model data, approximate change, and find the rate of change of a curve. In this program, Sharpie the Pencil shows students how to plot and sketch a linear graph from a linear equation and then how to derive a linear equation from a linear graph. In the process, the slope-intercept form of linear equation is illustrated, and the y-intercept and the gradient m are underscored as key ideas in determining the equation of a line.
