The locus represented by ( x y+y z=0 ) is

Options

  1. AA pair of perpendicular lines
  2. BA pair of parallel lines
  3. CA pair of parallel planes
  4. DA pair of perpendicular planes

Correct answer

D. A pair of perpendicular planes

Step-by-step solution

Given the locus [ array l x y+y z=0 y(x+z)=0 y ( x + z )=0 array ] Therefore, it represents a pair of perpendicular planes.
