Outcomes

8.5.C

Contrast bivariate sets of data that suggest a linear relationship with bivariate sets of data that do not suggest a linear relationship from a graphical representation

8.5.D

Use a trend line that approximates the linear relationship between bivariate sets of data to make predictions

8.5.F

Distinguish between proportional and non-proportional situations using tables, graphs, and equations in the form y = kx or y = mx + b, where b ≠ 0;

8.5.H

Identify examples of proportional and non-proportional functions that arise from mathematical and real-world problems

8.5.I

Write an equation in the form y = mx + b to model a linear relationship between two quantities using verbal, numerical, tabular, and graphical representations
