Anthony has added a trend line to the scatterplot below. Do you agree with where he put the line? Explain your reasoning.

A scatter plot, with a decreasing, line of best fit. There are 6 points above the line, 10 points below the line, with 1 point on the line. Points below the line are further away from the line, than the points above 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.
