a) Determine symmetric equations for the line= (-2, 3, 0) + t(-1, 1, 2).

b) Determine if the point (-3, 2, -2) lies on the line with parametric equations x = 1 - 2t, y = 4 - t, z = 2 + 3t.

c) Determine vector, parametric and, if possible, symmetric equations for the line through the point (2, 1, 3) with direction vector= (4, 2, 5).
