This hyperbola is centered at the origin. Find its equation.
Foci: (0,-9) and (0,9)
Vertices: (0,-7) and (0,7)

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
