Hi, i need help with only part 5 please.Thanks

Question 2. Consider the equation 3(x2 + y2)2 = 100xy. 1. (1 point) Show that (x, y) = (3, 1) is a solution to this equation. 2. (2 points) Show that if (0, yo) is a solution to this equation, then (yo, To) and (-To, -yo) are also solutions to this equation. 3. (4 points) Find dy da (3,1) 4. (2 points) Using your answer from part (2), deduce four points (x, y) such that dy dy dx (x,y) dx (3,1) dx 5. (1 point) What is [Note: You do not need to compute the derivative from scratch] dy (3, 1)
