Deriving the Regression Line with Algebra
Quintanilla, John A.
Mathematics Teacher, v110 n8 p594-598 Apr 2017
Exploration with spreadsheets and reliance on previous skills can lead students to determine the line of best fit. To perform linear regression on a set of data, students in Algebra 2 (or, in principle, Algebra 1) do not have to settle for using the mysterious "black box" of their graphing calculators (or other classroom technologies). Instead, inquisitive algebra students can derive the "line of best fit" by themselves, using techniques they already know.
