Given the following values, which point would be considered an outlier?
x 1, 2, 3, 4, 5, 6, 7, 8, 9
y 0.8, 2.1, 3.1, 3.8, 5.2, 8.4, 6.9, 8.1, 9

A. (2, 2.1)
B. (4, 3.8)
C. (6, 8.4)
D. (9, 9)

Option C, (6, 8.4)

Step-by-step explanation:

It would be option C because all of the other ones, both the y and x value is almost the same.  (2, 2.1) (4, 3.8) and (9, 9) are all really close in y and x values.  While (6, 8.4) has a y value that is over 2 more than x.

 Option C, (6, 8.4)
