JEE Math Practice Question
If the system of linear equations. $$8x + y + 4z = - 2$$ $$x + y + z = 0$$ $$\lambda x - 3y = \mu $$ has infinitely many solutions, then the distance of the point $$\left( {\lambda ,\mu , - {1 \over 2}} \right)$$ from the plane $$8x + y + 4z + 2 = 0$$ is :
- A.$$3\sqrt 5 $$
- B.4
- C.$${{26} \over 9}$$
- D.$${{10} \over 3}$$
