Dear HarveyKlaus,

I'm happy to respond. :-)

In all honesty, my friend, this question is a little easier than anything the GMAT Quant would ask. We know point Q is on the x-axis, so it has to have a y-coordinate of zero. We know there's a right angle at Q--PQ is perpendicular to the x-axis--so PQ must be vertical and parallel to the y-axis. Therefore, Q must have the exact same x-coordinate as does P.

Q = (-2, 0) OA = (A)

Here are some more GMAT-like questions on Coordinate Geometry:

Does all this make sense?

Q has x co-ordinate as of P and y co-ordinate as of R.
Q = (-2,0)
Hence, OA is (A).
