8.SP.2 Investigate patterns of association in bivariate data: Straight lines as models

Investigate patterns of association in bivariate data: 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.
