I need help with this

1) In the following assume that X and y are both functions. Given x = -2, y = 1, x = -4 determine y' for the following equation. by' + x2 = 2013ely 2) An object is moving in the clockwise direction around the unit circle a + y = 1 As it passes through the point ( ), Y ) , its y coordinate is decreasing at the rate of 4 units per second. At what rate is the x coordinate changing at this point
