Hi please help me with question 3 Thanks

Question 2. Consider the equation 3(x2 + y2)2 = 100ry. 1. (1 point) Show that (x, y) = (3, 1) is a solution to this equation. 2. (2 points) Show that if (To, yo) is a solution to this equation, then (yo, To) and (-To, -yo) are also solutions to this equation. 3. (4 points) Find dy dx (3,1) dy dy 4. (2 points) Using your answer from part (2), deduce four points (x, y) such that dx (z,y) dr (3.1) dx 5. (1 point) What is [Note: You do not need to compute the derivative from scratch] dy (3, 1)
