Find the equation of the plane passin...

Find the equation of the plane passing through the point `(2,3,1)` having `(5,3,2)` as the direction ratio is of the normal to the plane.

Text Solution

Verified by Experts

Let the equation of a plane passing through the point` (2,3,1)` is
`a(x−2)+b(y−3)+c(z−1)=0....(1)` where `a,b,c `are the d.rs of the normal to the plane of (1).
Given` a,b,c` are proportional to `5,3,2.`
Then` a=5k,b=3k,c=2k`
