Kiley gathered the data in the table. She found the approximate line of best fit to be y = 1.6x – 4.What is the residual value when x = 3?–1.8–

Accepted Solution

Answer:–1.8 Step-by-step explanation:A residual is the distance between an observed (actual) point and a predicted value.  To make the prediction, we substitute 3 in for x in our line of best fit:y = 1.6(3) - 4 = 4.8 - 4 = 0.8To find the residual, we subtract the actual value and the predicted value:-1-0.8 = -1.8
