Because In this problem we don’t need to know the equation of the regression line. The line best fits the data (predicted values) to be as close to the actual (observed values) as possible. The differences between the predicted values and the observed values should appear as the vertical distances between each observed value and its predicted value. The line that minimizes the sum of the squares of the distances is the best fit line, or regression line, we are looking for. The correct answer is graph B.

Yes, that is mathematical way to interpret the solution. But it is for the teachers, professional readers, not for us, the students. To us, we know what is "the best fit" is good enough, how to find it out is good enough, right??
