Lesson 3 is about a super important topic when learning about lines in algebra- the topic is “slope”.  The slope of a line is the angle of the line and we really need to understand the slope to graph lines and find the equation of a line.  By the way I have been talking about graphing and finding the equation of lines- these “line” equations have a mathematical name called “linear equations”.  So this chapter is really all about linear equations and slope.

Things to focus on in this lesson:

• the definition of slope
• the rise over the run
• how to find the slope given two points
