Select the equations that are parallel and perpendicular to y = x + 7 and that pass through the point (-8, 9).

parallel: y = x - 11
perpendicular: y = -4x + 23

parallel: y = -4x + 11
perpendicular: y = x - 4

parallel: y = 4x - 7
perpendicular: y = x - 7

parallel: y = x + 11
perpendicular: y = -4x - 23
