Videos and lessons to help Grade 8 students know that straight
lines are widely used to model relationships between two
quantitative variables. For scatter plots 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.

Common Core: 8.SP.2

- I can show how straight lines are used to model relationships between two quantitative variables.
- I can informally assess the model fit by judging the closeness of the data points to the line
- I can fit a straight line within the plotted data.
