Scatter Plots Best Line of Fit Linear Review

If a scatterplot has no association then...

• ...it has no ordered pairs

• ...it has ordered pairs that have a negative pattern

• ...its ordered pairs have no predictable pattern

• ...if it makes a lion on a graph (roar!)

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 pass through two points.

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

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