The equation of a plane containing the point (1,-1,1) and parallel to the plane 2 x+3 y-4 z=17 is
Options
- Ar (2 -3 -4 k )=-1
- Br ( - j + k )=3
- Cr (2 +3 -4 k )=-5
- Dr (2 +3 -4 k )=5
Correct answer
C. r (2 +3 -4 k )=-5
Step-by-step solution
Here a = i - j + k & n =2 i +3 j -4 k Now a n =2-3-4=-5 Vector equation of plane passing through A ( a ) is aligned & r n = a n & r (2 i +3 j -4 k )=-5 aligned
