Samantha constructs a scatter plot. She realizes that she needs to add one more point, which will be an outlier. Which of the ordered pairs does she still need to plot?

(19,9)

(8,6)

(10,14)

(4,15)
Coordinate plane with horizontal axis labeled Variable X and vertical axis labeled Variable Y. The following ordered pairs, which are approximated, are plotted 2.5 comma 15, 5 comma 15, 6 comma 12, 7 comma 14, 10 comma 12, 11 comma 12, 12.5 comma 11, 13 comma 11, 16.5 comma 9, and 19 comma 7.

The coordinates are (19, 9), (10,14)   and (4,15)

Given the ordered pairs that Samantha needs to plot given as shown;

From the given ordered pair, we can see that the outlier is (8, 6) because it lies an abnormal distance from other coordinate points.

We can see that as the x-values is increasing, the y-values is decreasing. Hence the ordered pairs that she still needs to plot are the remaining coordinate order than the outlier.

The coordinates are (19, 9), (10,14)   and (4,15)
