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

Answer:

the answer is: '-2'

Step-by-step 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.
