Find the equation of a plane which passes through thepoint (3, 2, 0) and contains the line `(x-3)/1=(y-6)/5=(z-4)/4dot`A. `x-y+z=1`B. `x+y+z=5`C. `x+2y-z=1`D. `2x-y+z=5`

Answer» Correct Answer - a
The required plane is `|[x-3,y-6,z-4],[3-3,2-6,0-4],[1,5,4]|=0`
or `|[x-3,y-z-2,z-4],[0,0,-4],[1,1,4]|=0`
`("Operating"C_(2)toC_(2)-C_(3))`
or `4(x-3-y+z+2)=0`
or `x-y+z=1`
