Step-by-step explanation:
The value farthest away from the line best of fit has a greatest value. Therefore you find the value that is the greatest and that value is the farthest away from the line of best fit.
Out of the values .19, .7, 2, 8
8 is the greatest value from this set. Therefore, 8 is the farthest away from line of best fit.
