College Board · Accepted Answer

The correct answer is A. Choice A is correct. The data point with x = 1 has a y -coordinate of 12 . The y -value predicted by the line of best fit at x = 1 is approximately 11 . The difference between the y -coordinate of the data point and the y -value predicted by the line of best fit at x = 1 is 12 - 11 , or 1 .
