8.SP.2 - Scattter Plots and Best Fit Lines - Know that straight lines are widely used to model relationships between two quantitative variables. For scatterplots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line.

The table from 8.SP.1made this graph
|
This is just the data converted to points and the points put onto a coordinate plane.
|
And this is the best fit line for the graph
|
The best-fit line sort of "splits" the data down the middle and shows a trend as to what the data would be like if you had to use a line to describe it.
