One side of a rectangle lies along the line 4x+7y+5=0.
Two of its vertices are (-3,1) and (1,1). Which of the foolowing is not an equation of the other three straight lines?
a)14x-8y=6
b)7x-4y=-25
c)4x+7y=11
d)14x-8y=20

• and d) check by options
  line in c) is parallel to the given line and passes through (1,1)
  line in a) and b) are perpendicular to given line and passes through (1,1) and (-3,1) respectively
  hence d
