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. 

A first quadrant scatterplot where the points are very scattered, with a decreasing line. There are 6 points above the line, following the line fairly closely, 10 points below the line, with many points not following the line, and 1 point on the line.

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

Are approximately half the data points on each side of the trend line?

The line is slightly lower to the left and less steep.
