Take the cross product, then normalize the result.

This has norm

and so a unit vector orthogonal to both given vectors is

An equally correct answer would be the negative of this vector, since

.
Answer: Because Point A is negative and the same distance below 0 on the number line as Point B is above it, Point B is both positive and the opposite of Point A.
The first one. It is called an exponential decay curve.
