The equation of a plane passing through ...

The equation of a plane passing through the point A(2,-3,7) and making equal intercepts on the axes,is

A

`x+y+z=3`

B

`x+y+z=6`

C

`x+y+z=9`

D

`x+y+z=4`

Text Solution

Verified by Experts

The correct Answer is:
b
Let the required equation of the plane be `x/a+y/z+z/a=1`, i.e., `x+y+z=a`.
Since, it passes through the point A(2,-3,7), we have `2+(-3)+7 =a rArr a=6`.
Hence, the required equation of the plane is `x+y+z=6`.
