Question

What is the center of the following graph?

	A.	(2, 2)
	B.	(-2, 0)
	C.	(1, 3)
	D.	(3, 1)

 

Answer 1

From the graph, the ellipse is horizontal.

The major axis : 2a = 6 ----> a = 3.

The minor axis : 2b = 4 ----> b = 2.

Vertices : (- 1, 2) and (5, 2)

Co-vertices : (2, 0) and (2, 4)

Center : (h, k) = The mid point of the vertices or co-vertices.

(h, k) = [(2 + 2)/4, (0 + 4)/2]

(h, k) = (2, 2)

The option A is correct.
