Question

Melissa collected the data in the table.

Answer 1

A residual is the difference between the actual value and the predicted value. If there is a scatter plot with a line of best fit, the residual would be the vertical distance between the actual point and the line of best fit.

For our question, the table already gives the "given" and "predicted" values. Hence, the residual is the different between the "given" and "predicted" values.

If you look at the first three rows, you will see that residual = given - predicted.

So, when $x=4$, residual = $9-10=-1$. Answer choice B is correct one.

ANSWER: B

Answer 2

When x=4 b) -1  (9-10=-1)
