JEE Math Practice Question
Two lines $${{x - 3} \over 1} = {{y + 1} \over 3} = {{z - 6} \over { - 1}}$$ and $${{x + 5} \over 7} = {{y - 2} \over { - 6}} = {{z - 3} \over 4}$$ intersect at the point R. The reflection of R in the xy-plane has coordinates :
- A.(2, 4, 7)
- B.(2, $$-$$ 4, $$-$$7)
- C.(2, $$-$$ 4, 7)
- D.($$-$$ 2, 4, 7)
