The equation of the line ý = -14.7+1.59x is called the
least-squares regression line because it
O passes through each data point.
O is least able to make accurate predictions for the
data.
O minimizes the sum of the squared vertical distances
from the points to the line
O maximizes the sum of the squared vertical distances
from the points to the line.
