Question

In the space the equation $by + cz + d = 0$ represents a plane perpendicular to the plane

• A. $YOZ$
• B. $Z = k$
• C. $ZOX$
• D. $XOY$

Answer 1

Answer: (A)

$YOZ$

Answer 2

The equation of yz-plane is x = 0. i.e., $x + 0 . y + 0 . z = 0$ .

Clearly, given plane is perpendicular to yz-plane.
