The Cartesian equation of the plane passing through the point A (7,8,6) and parallel to the XY plane is

Options

  1. Az=1
  2. By=8
  3. Cx=7
  4. Dz=6

Correct answer

D. z=6

Step-by-step solution

The required plane passes through the point (7,8,6) and is parallel to XY plane. It is perpendicular to z axis and direction ratios of z axis are 0,0,1 . Required equation of plane is 0( x -7)+0( y -8)+1( z -6)=0 z =6
