Answer:
The residual of the point in the equation
is
Step-by-step explanation:
We have been given point where
.
Now the equation is .
Plugging the value of in the equation of
,
we have to find the predicted value of y and .
So y predicted .
To find the residual point we have to subtract the actual value from the predicted value.
As actual value of along with the points
.
Residual point = Actual value - Predicted value.
So the residual for the point is
.
