Use the four standard forms to find the equation of the parabola with vertex at the origin and with the follow properties:
a) axis vertical, passing through (4,1)
b) axis horizontal, passing through (2,-2)

I don't understand what it means by axis vertical/horizontal, if anybody can clarify this for me would be great!
Thanks :D

axis = axis of symmetry which then dictates the orientation of the parabola (either left-right or up-down)
