Find a vector equation and parametric equations for the line segment that joins P to Q. P(-3, 8, 0), Q(5, -1, 8).
a) r(t) = (-3+8t, 8-9t, 0+8t), Parametric equations: x = -3+8t, y = 8-9t, z = 0+8t
b) r(t) = (8t, -9t, 8t), Parametric equations: x = 8t, y = -9t, z = 8t
c) r(t) = (-3-5t, 8+7t, 0+8t), Parametric equations: x = -3-5t, y = 8+7t, z = 0+8t
d) None of the above
