CPM Homework Help : CC3MN Problem 7-92

Anthony has added a line of best fit to the scatterplot at right. Do you agree with where he put the line? Explain your reasoning.

The trend line is the best fit line for all the points and the shortest distance from each of the points on the plot.

More Help:
