Introduction to Slope_Equations of Lines

This video reviews slope at the beginning. Before watching this video it would be wise to first watch my video "Introduction to Slope". I discuss slope of all types including horizontal and vertical lines. I show how to calculate slope from a graph and given 2 points. I then discuss slope intercept form of a line, y = mx + b, which applies to all but vertical lines, which I also discuss. I show how to find the equation of a line from a graph and when given 2 points.
