A student draws a line to model a set of data points.

Which statement is true?

• The student's drawing is the best fit possible for the data because it intersects a data point that is close to many other data points.

• The student's drawing is the best fit possible for the data because the line interesects the origin

• The student's drawing would fit the data better if the line minimized the distance to each data point

• The student's drawing would fit the data better if the line was above all of the data points.
