Question

The equation of the plane through the line of intersection of planes ax + by + cz + d = 0, a'x + b'y + c'z + d' = 0 are parallel to the line y = 0, z = 0 is

(a)  (ab' – a'b)x + (bc' – b'c)y + (ad' – a'd) = 0

(b)  (ab' – a'b)x + (bc' – b'c)y + (ad' – a'd)z = 0

(c)  (ab' – a'b)y + (ac' – a'c)z + (ad' – a'd) = 0

(d)  None of these

Answer 1

Correct option (c) (ab' – a'b)y + (ac' – a'c)z + (ad' – a'd) = 0
