Graphing a Linear Equation Using Slope

How would you figure out the total amount of money someone is willing to donate to you for every mile you run? Likely you can come up with some pretty good ideas, based on your knowledge of algebra. In this topic, you will discover ways to solve real world problems such as this, by learning more about the slope of a line. Before you can solve this particular problem, you will explore specific ways to describe slope, and then learn how to graph linear equations in slope-intercept form. You will also graph parallel and perpendicular lines.
