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

Options

  1. Az=7
  2. Bz=8
  3. Cz=6
  4. Dz=4

Correct answer

C. z=6

Step-by-step solution

Planes parallel to the XY -plane have equations of the form z = k where k is constant. The plane passes through A(7,8,6) , so its z-coordinate must satisfy the plane equation: k = 6 . The resulting equation is z = 6 , which corresponds to option C.
