A plane meets the coordinate axes at A ,...

A plane meets the coordinate axes at `A ,Ba n dC` respectively such that the centroid of triangle `A B C` is `(1,-2,3)dot` Find the equation of the plane.

Text Solution

Verified by Experts

Since they meet at A,B,C so,
`A/3=B/3=C/3=(1,-2,3)`
So,
`A=3 B=-6 and C=9`
Thus,
equation are,
`x/(3)=y/(-6)=z/9=1`
