The Least-Squares Regression Line (LSRL) is the line that minimizes this sum. The equation of the LSRL is . represents explanatory variable (actual data). represents predicted y-value. represents y-intercept. represents slope. Given a set of data, you can calculate the LSRL (without using your calculator!).
