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 is
,and when we substitute the value into the given equation
we get
so, the residual value is given as:
Hence, the residual value at x=-2 is -2.
