This shows the second method for factoring a trinomial where a is not = 1


A couple of examples of factoring a common factor first and then factoring further if possible.


This video explains the rectangular coordinate system and labels its parts, then shows how to plot points.


This video explains the slopes of horizontal and vertical lines.


Given y=mx + b, this video shows how to use the bvalue to create the yintercept and then use the slope to find other points.
