Powerpoint lesson which teaches students how to generate coordinates for a graph of the form y=mx+c. Then how to plot them on squared paper before joining them up to form a straight line. The powerpoint then moves on to show how only three coordinates are needed when drawing straight lines. The last slide is a set of questions I have taken from my Algebra booklet which can be used in class. However I plan on putting the booklet onto this site in the coming months.
