If the origin and the points (1,2,3),(2,3,4) and (x, y, z) are coplanar, then

Options

  1. Ax-2 y+z=0
  2. Bx+y+z=6
  3. Cx-2 y+z+1=0
  4. Dz-2 x+y=0

Correct answer

A. x-2 y+z=0

Step-by-step solution

For give coplanar points, we write aligned & | array lll 1 & 2 & 3 2 & 3 & 4 x & y & z array |=0 & x(8-9)-y(4-6)+z(3-4)=0 &-x+2 y-z=0 x-2 y+z=0 aligned
