Alexa created the line of best fit shown for the data points graphed. Is the line a good representation for this data? Explain your reasoning.
A graph is shown in the xy-plane. the values on the x-axis range from 0 to 18 in increments of 2 and the values on the y-axis range from 0 to 20 in increments of 2. Several points are scattered on the graph and a line is shown which starts from the origin and goes up. The line is such that the concentration of points on its left is more than on its right.

I said no because most of the points are over the line for it to be a good representation the line has to have about the same amount or the same amount of points over and under the line
