Answer 1

SOLUTION

Given;

Suppose the line of best fit is drawn for some data points. If the mean of the

x-coordinates of the points is 5, and the mean of the y-coordinates of the

points is - 7 the line must pass through which of these points?

Explanation:

The 'line of best fit' is a line that goes roughly through the middle of all the scatter points on a graph.

$The\text{ middle of all points is simply the mean.}$

Final answer:
