Peter attempted to use the divide-center method to find the line of best fit on a scatterplot what was his mistake

The dotted line does not divide the data in two as the left and right side have an unequal, odd number of points 3 and 5 respectively

Step-by-step explanation:

The steps to follow in the divide the center method includes

1) Plot data

2) A dotted line is then drawn that divides the data in two, such that each side has an even number count of points

3) Mark the center of the data on each side of the dotted line as x

4) Draw a straight line through the x marks to extend to the plot area edges

5) The line drawn is the line of best fit.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
