Question

The line joining the points A(2,1,3) and B(-1,2,4) meets YZ and ZX planes at the point C and D respectively. Find the coordinates of C and D​

Answer 1

Answer:

Let the YZ plane divide 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

(

k+1

k(3)−2

,

k+1

k(−5)+4

,

k+1

k(8)+7

)

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

⇒

k+1

3k−2

=0

⇒3k−2=0

⇒k=

3

2

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