Step-by-step explanation:
Let m : n be the ratio in which the line joining the points (-1, 1, -8) and (5, -2, 10) is divided by the ZX plane at a point P (let).
Then, the co-ordinates of the point P are given by
Since the point P lies on the ZX plane, so its y co-ordinate will be zero.
That is, we must have
Therefore, the x and z co-ordinates of P are
Thus, the required co-ordinates of the point are (-3, 0, 6).
