Q. Let the equations of a line and a plane be $\frac{x + 3}{2} = \frac{y - 4}{3} = \frac{\mathcal{z} + 5}{2}$ and $4x - 2y - \mathcal{z} = 1$, respectively, the

A) The line is parallel to the plane
B) The line is perpendicular to the plane
C) The line lies in the plane
D) None of these
Explanation

(a)
$4(2) - 2(3) - 1(2) = 0$
Also, point $( - 3,\ 4,\ - 5)$ does not lie on the plane
Therefore, the line is parallel to the plane
