1.	Consider the line L given by the equation x−32=y−11=z−21. Let Q be the mirror image of the point (2,3,–1) with respect to L. Let a plane P be such that it passes through Q, and the line L is perpendicular to P. Then which of the following points is on the plane P:
Answer» Consider the line $L$ given by the equation $\frac{x - 3}{2} = \frac{y - 1}{1} = \frac{z - 2}{1} .$ Let $Q$ be the mirror image of the point $(2, 3, - 1)$ with respect to $L .$ Let a plane $P$ be such that it passes through $Q,$ and the line $L$ is perpendicular to $P .$ Then which of the following points is on the plane $P$ :
