Standard - NY-8.SP.1:
Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.

Standard - NY-8.SP.2:
Understand 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.

Standard - NY-8.SP.3:
Use the equation of a linear model to solve problems in the context of bivariate measurement data, interpreting the slope and intercept.
