    Yes. These vectors determine the same plane as the vectors <3, 1, 2> and <0, -1, 1>. To check yourself, take the cross product of the two pairs of vectors. Each cross product gives you a normal to a plane that contains the two vectors.

    You get different vectors, but each is a scalar multiple of the other, so each of the two planes is the same.
