Two parallel lines Land Ly undergo a rigid transformation. For which scenario are the transformed lines L and L', always parallel? O Li is translated 4 units down, and L2 is rotated 90' clockwise about the origin.
O L is translated 2 units to the right, and L2 is translated 2 units to the left.
O Li is rotated 90 clockwise about the origin, and L, is rotated 180° about the origin.
O L is reflected across the y-axis, and L2 is translated 3 units up.
