Question

The approximate line of best fit for the given data points, y = −2x − 2, is shown on the graph.

Which is the residual value when x = –2?


A.–2

B.–1

C.1

D.2

Answer 1

-2 i just took the test on edge i got 100%

Explanation:

Answer 2

the answer is: '-2'

Explanation:

" A residual value is a difference between observed y-value(from scatter plot) and the predicted y-value( from regression equation line) ".

when we look at the scatter plot we see that the value of y at
`x= -2` is
`y=0`

,and when we substitute the value
`x=-2` into the given equation
`y= -2x-2`

we get
`y=2.`

so, the residual value is given as:
`y=0-2= -2.`

Hence, the residual value at x=-2 is -2.
