Find parametric equations of the streamline of the velocity field v(x, y, z) = y i - y j + y k that passes through the point (2, -3, -4).
◦ x = 2 + t, y = -3 - t, z = -4 - t
◦ x = 2 + t, y = -3 - t, z = -4 + t
◦ x = 2t, y = -3t, z = -4t
◦ x = 2 + t, y = 3 - t, z = 4 + t
◦ x = 2 + t, y = -3 + t, z = -4 + t
