Question

Suppose the line of best fit is drawn for some data points. If the mean of thex-coordinates of the points is 5, and the mean of the y-coordinates of thepoints is - 7 the line must pass through which of these points?A. (-7,5)B. (7-5)C. (5, -7)D. (-5,7)

Answer 1

C. (5, -7)

Explanation:

You want to know the point that lies on the line of best fit if µx = 5 and µy = -7.

Line of best fit

The line of best fit will go through the point (µx, µy). For the given means, the line of best fit must pass through the point (5, -7).
