A point is moving on the graph of 5x³ +6y³ = = xy. When the e point is at (1), its y-coordinate is (D) increasing at a speed of 5 units per second. What is the speed of the x-coordinate at that time and in which direction is the x-coordinate moving? 17 17 (A) 8 units/sec, increasing x (B) units/sec, decreasing x units/sec, increasing x 2 2 33 35 units/sec, decreasing x (E) 8 units/sec, decreasing x (F) units/sec, decreasing x 4
