Select the equations that are parallel and perpendicular to y = 2x - 1 and that pass through the point (4, 1).

parallel: y = 2x - 7
perpendicular: y = -1/2x + 3

parallel: y = 2x + 2
perpendicular: y = -1/2x + four and one half

parallel: y = -1/2x - 7
perpendicular: y = 2x + 3

parallel: y = -2x - 7
perpendicular: y = -1/2x - 1
