Answer:
The linear approximation is ;
F(x,y) = x -5y - 1
Explanation:
Here, we want to find the linear approximation of the given function at the indicated point.
We start by substituting the values then after wards finding the partial derivative with respect to x and then to y.
We finish by adding up these values after substituting the values of x and y into the differentiated partial equation. We then add up our results.
