If the line meets the plane, x + 2y + 3z = 15 at a point P, then the distance of P from the origin is :
C.
Let P(2t + 1, 3t - 1, 4t + 2 )be any point on the line, P lies on plane also
A plane passing through the points (0, - 1, 0) and (0, 0, 1) and making an angle with the plane y - z + 5 = 0, also passes through the point :
