You just have to put the price on y-axis (up and down) and the quantity sold on the x-axis (left to right) and then draw through both points on the graph, and you have a linear demand curve.

Abstract: In this paper, a new methodology for curve approximation is presented. The method is suitable for both self-intersected and non self-intersected curves, it combines elements from graph ...

which approximates principal curves of data sets by piecewise linear curves. The polygonal line algorithm is extended to find principal graphs and complemented with two steps specific to the task of ...
