The lesson is on the slope of lines; this might be a little bit of a review for you from algebra. Slope is the ratio between the vertical and the horizontal, or we can say 'rise over run.' Rise is going up and down and the run is going left and right. So, when we talk about slope, we are talking about the vertical change and the horizontal change. You'll learn the formula for the slope m of a line containing two given points. This lesson also covers a couple of postulates regarding slope. The first one tells us more about lines that have the same slope, and the other one tells us about perpendicular lines and their slopes.
