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?

a.–1.8

b.–0.2

c.0.2

d.1.8

 The difference between the observed value of the dependent variable (y) and the predicted value (ŷ) is called the residual (e). When x is equal to 3, the value of y from the best fit line would be 0.8. Therefore, the residual would be -1 - 0.8 = -1.8. Option A is the correct answer.

Then why is the question on here if you know the answer
