Write the ratio in which YZ plane divide...

Write the ratio in which YZ plane divides the segment joining`" P"(-2," "5," "9)"and\ Q"(3," "-2," "4)dot`

Text Solution

Verified by Experts

The distance of a general point `P(x, y, z)` from `X Y`-plane is `z`.

Thus, distance of `(7,-2,3)` from `X Y`-plane is `3 .`

Similarly, the distance of `P(x, y, z)` from `Y Z`-plane is `x`.

Thus, distance of `(7,-2,3)` from `Y Z` - plane is `7 .`

The distance of `P(x, y, z)` from `X Z`-plane is `y`.

Thus, distance of `(7,-2,3)` from `X Z`-plane is 2 .
