Question

Look at the data in the table.
x y
2.4 9
7.2 28
7 24
8.3 35
3.1 9
7.2 30
9 32

Which graph shows the line of best fit for this data?

Answer 1

Given table

______

x         y

______

2.4     9

7.2     28

7         24

8.3      35

3.1      9

7.2     30

9        32

_________

So, the coordinates on the graph (2.4, 9), (7.2, 28), (7, 24), (8.3, 35),  (3.1 , 9), ( 7.2, 30), (9, 32).

The first graph represents the line of best fit.

The definition of line of best fit " A line of best fit is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points.".

Note: Most of the points should be as closer as possible to the drawn line.

Answer 2

I think it is the first, or second graph.
