Scatter Plots and Tables

John plotted points on a graph to see if there was a relationship. Then he drew a line of best fit based on the fact that his line went through the most points possible.

Decide whether which statements are False.

• John's line of best fit is correct.

• John's line of best fit should be higher to be closer to all of the points.

Select the statement that best describes the line.

• The line is the line of best fit.

• The line is NOT a line of best fit because it does not go through the origin.

• The line is NOT a line of best fit because it does not go through the middle of the data set.
