Question

If the distance of the point $P (1, - 2, 1)$ from the plane $x + 2 y - 2 z = α, w h e r e α > 0, i s 5,$ then the foot of the perpendicular from $P$ to the place is a. $(\frac{8}{3}, \frac{4}{3}, - \frac{7}{3})$ b. $(\frac{4}{3}, - \frac{4}{3}, \frac{1}{3})$ c. $(\frac{1}{3}, \frac{2}{3}, \frac{10}{3})$ d. $(\frac{2}{3}, - \frac{1}{3}, - \frac{5}{3})$
