So the line of best fit in the figure corresponds to the direction of maximum uncorrelated variation, which is not necessarily the same as the regression line. You are correct: it is the line which minimizes the sum of the squares of the perpendicular distance between each point and the line.
Students will be able to plot data that they have collected on a graph. They will construct a line of best fit (regression line) to model their data. They will be able to interpret the slope and intercept of the regression line they calculated.

The line of best fit can be thought of as our estimate of the regression line. “Best fit” is not a precise term, since there are many ways to define it (ie using a least squares criterion, minimizing the absolute values of the residuals etc.). One desirable property for the line of best fit to have is for.
