Answer:

Either (20,20) or (10,38) , more to (10, 38).

Explanation:

Data are often shown in a table or as a list of ordered pairs. One way to identify outliers in these situations is to build a scatter plot and identify points that do not fit the general pattern of the data. It is also possible to identify potential outliers without creating a scatter plot. In this case, it helps to organize the data using the coordinates.

Consider the following set of data, listed with the x-values in increasing order.

{(−6,−10),(−1,−2),(2,4),(5,−99),(9,12),(13,20)}

The general pattern is that as the x-values increase, the y-values also increase. However, for the point (5,−99), the y-value is much lower than the other y-values. This means the point is likely an outlier. (EXAMPLE!) Use this to completely solve your equation.
