Question

find the ratio in which the y-z plane divides the line segment from by joining the points (-2,4,7)& (3,-5,8)

Answer 1

Let the YZ planedivide the line segment joining points (–2, 4, 7) and (3, –5, 8) in the ratio k:1.

Hence, by section formula, the coordinates of point of intersection are given by

On the YZ plane, the x-coordinate of any point is zero.



Thus, the YZ plane divides the line segment formed by joining the given points in the ratio 2:3.
