In this lesson I will teach you about best fitting lines and scatter plots. This topic is really a key application of everything we have learned about finding the equation of lines. You want to have some graph paper when you learn and practice this skill because you will need to estimate data from a graph. Also I would suggest using the point-slope formula to find the actual equation of the line once you determined the “best” data to use. This topic has a lot of real world application in business and science so it’s a nice example of how math is so important in many areas of study.
