These 3 problems are perfect for introducing students to finding the linear equation of a best fit line. The problems ensure students understand the meaning behind the correlation coefficient and the y-intercept. This helps students realize the importance of the linear equation. The extensive problems help review concepts that are important for successfully writing a y = mx + b equation for a best fit line.
The answer key provides the exemplar for problem #1. If you want all students getting the same answers, you may want to pre-draw the best fit lines. Enjoy!
