I've got some homework about ellipses and I am not sure if I am doing these right. So if you could check my answers I would appreciate it. Thanks!!
1.) Write an equation for an ellipse if the endpoints of the major axis are at (1,6) and (1,6) and the endpoints of the minor axis are at (5,0) and (3,0).
A.) (x1)^2/36 + y^2/16 = 1
B.) (x+1)^2/36 + y^2/16 = 1
C.) y^2/36 + (x1)^2/16 = 1
D.) y^2/36 + x^2/16 =1
**My answer is D.
2.) Which is the equation of an ellipse with center (4,2) and a horizontal major axis?
A.) (x4)^2/16 + (y2)^2/4 = 1
B.) (x+4)^2/16 + (y2)^2/4 = 1
C.) (y+2)^2/16 + (x+4)^2/4 = 1
D.) (y2)^2/16 + (x4)^2/4 = 1
**My answer is B.

1) the center is (1, 0), not (0, 0)
notice that the major coordinates are not (0, 6) and (0,6).
2) correct!
