Question

Which two points should the line of best fit go through to best represent the data in the scatterplot? On a graph, points are at (1, 16), (2, 15), (3, 14), (4, 9), (5, 8), and (6, 1). (1, 16) and (2, 15) (1, 16) and (6, 1) (2, 15) and (4, 9) (5, 8) and (6, 1)

Answer 1

• Answer:

C. (2, 15) and (4, 9)

Answer 2

C. (2, 15) and (4, 9)

Explanation:

The line of best fit in a scatterplot is a straight line that shows the relationship among the data. It is drawn in such a way that it groups the points evenly on each side of the line. It is used when a straight line could not be drawn through all or major number of points plotted on the graph.

From the question, when points (1, 16), (2, 15), (3, 14), (4, 9), (5, 8), and (6, 1) are plotted on a graph, the line of best fit would go through points (2, 15) and (4, 9). This would achieve an even spread of the points on the two sides of the line.
