Consider the line given by the parametric equation
x = 5 - 2t, y = 3 + t, z = 4t
and the plane ax + by + cz = d. Find values for a, b, c and d such that:
(a) The plane is perpendicular to the line.
(b) The plane is perpendicular to the line and passes through the point (5, 3, 0).
(c) The plane is parallel to the line.
