Question

The co-ordinates of the point in which line joining $(1, 1, 1)$ and $(2, 2, 2)$ intersects the plane $x + y + z = 9$ are

• A. (3, 4, 2)
• B. (2, 3, 4)
• C. (3, 2, 4)
• D. (3, 3, 3)

Hint:

If a line passes through the origin or has $x=y=z$ form, and the plane is $x+y+z=d$, the intersection point is always $(d/3, d/3, d/3)$.
