Best Fitting Lines And Scatter Plots

Good news! Sometimes in algebra you get to guess- well not totally but kind of.  Finding the “best fitting line” is an example when we estimate the best line that over laps a trend of points on a graph. What you do is use your best judgment to find a set of points ( 2 points to be exact) that when you connect them and draw a line “fit” the trend of all the points pretty well.  Now when you find your two points, you then need to find the equation of a line based on that data.  This is a basic explanation of best fitting lines I have a great video on this if you go to my youtube channel and search the topic.


 

 

some key topics that involve finding the best fitting line:

* point-slope formula
* slope-intercept formula
* slope
* linear models
* scatter plots
