The electrical potential at any point (x, y) on a plate is given by V(x, y) = 50x + x + y + 2. (a)

The electrical potential at any point (x, y) on a plate is given by V(x, y) = 50x² + x + y² + 2.
(a) At the point (1,-1), in what direction is the electric potential increasing most rapidly? Draw an arrow on the grid indicating this direction.
