A) \[7x-y+5z+75=0\]
B) \[7x+y-5z+73=0\]
C) \[7x+y+5z+73=0\]
D) \[7x-y-5z+75=0\]
E) \[7x-y-5z+73=0\]
Correct Answer: A
Solution :
Equation of any plane passing through\[(-7,1,-5)\]is \[a(x+7)+b(y-1)+c(z+5)=0\] ?.(i) The DRs of normal to above plane are \[a=-7,b=1,c=-5\] \[\therefore \]From Eq. (i), we get \[-7(x+7)+1(y-1)-5(z+5)=0\] \[\Rightarrow \] \[-7x+y-5z-75=0\] \[\Rightarrow \] \[7x-y+5z+75=0\]You need to login to perform this action.
