The Maths Prof: Finding Equations of Straight Lines

In this lesson I show you how to find the equation of a straight line when you know the coordinates of two different points along that line. You can use this method when the coordinates of two points have been given to you, or, by selecting two points yourself when presented with a diagram of the graph.
