Scatterplot

Number of years owned is on the horizontal axis and Value (1,000s of $) is on the vertical axis.

The number of years owned range from 0 to 21, thus an appropriate scale for the horizontal axis is from —3 to 22.

The value (1,000s of $) range from 80 to 119, thus an appropriate scale for the vertical axis is from 75 to 125.

Step 2

There appear to be two outliers at 15 and 18 years, because the corresponding points lie far above the general pattern in the other points.

Result:

Two outliers.
