Represent bivariate data on a scatter plot, and describe how the variables’ values are related.
It’s important to keep in mind that the data must be linked to the same “subjects,” not just two unrelated quantitative variables; being careful not to assume a relationship between the actual variables (correlation/causation issue).
a. Fit a function to real-world data; use functions fitted to data to solve problems in the context of the data.
Algebra I emphasis is on linear models and includes the regression capabilities of the calculator.

AII

Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.  a. Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear and exponential models. b. Informally assess the fit of a function by plotting and analyzing residuals. c. Fit a linear function for a scatter plot that suggests a linear association.
