Question

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

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

b)parallel: y = 2x + 2
perpendicular: y = -1/2 x + 4 1/2

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

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

Answer 1

Your going to have to graph them

Answer 2

i dont know how
