longer. You have four points whose coordinates will satisfy the correct equation: (0,3),(0,–3), (2,0),
and (–2,0). The only choice that works with all of these points is (D).
Every once in a while, a hyperbola turns up on the Math 2 test. Here’s an equation of a hyperbola. It
looks a lot like the equation for an ellipse, except that there’s a minus sign.
You’ve covered the coordinate geometry topics that you’re likely to encounter on the Math 2 test.
You’ve reviewed the facts and formulas and learned some useful strategies. You may also see a
question on one of the following.
HYPERBOLA
The equation of a hyperbola centered at the origin and with foci on the x-axis is:
The hyperbola
is centered at the point (h,k).
COORDINATES IN THREE DIMENSIONS
It’s possible that you’ll see a question involving a third dimension in coordinate geometry. Doing
coordinate geometry in three dimensions is very similar to working in two dimensions.
