find the standard form of the equation of the hyperbola with center 0,0 vertices (+/- 3,0) and foci (+/-3 square root 5, 0)

i know it is either

x^2 over 9 - y^2 over 45 =1

or

y^2 over 9 - x^2 over 45 =1

how to tell if x or y comes first

if it's horizontal a^2 is under x^2
if it's vertical a^2 is under y^2
look at the coordinates, is it changing horizontally or vertically
