The least squares regression line minimizes the sum of the

The squared vertical distances (residuals)

Explanation:

The least square regressions line in any given graph is used in determining the line of best fit. The line of best fit refers to the maximum number of points/coordinates the line is able to pass through.

The least square regression line helps in minimizing the sum of the squared vertical distances . This helps in avoiding issues of negative sign distances.
