Answer the following:

3) Consider the curve given by the equation y' - xy = 2. It can be shown that dy dx 3y- - x (a) Write an equation for the line tangent to the curve at the point (-1, 1). (b) Find the coordinates of all points on the curve at which the line tangent to the curve at that point is vertical. (c) Evaluate d' y at the point on the curve where x = -1 and y = 1. dx
