1) What are the co-vertices of the following graph?

(0, 1) and (0, -1)

(1, 0) and (-1, 0)

(0, 8) and (0, -8)

(8, 0) and (-8, 0)

2) What is the equation of the following graph?

(x+1)^2/9 - (y-2)^2/16 = 1

(x-1)^2/9 - (y+2)^2/16 = 1

(y+2)^2/16 - (x-1)^2/9 = 1

(y-2)^2/16 - (x+1)^2/9 = 1

3) What is the center of the following graph?

(-1, -2)

(2, 0)

- Each graph is in order by each number below:
