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
.
