A software designer is mapping the streets for a new racing game. All of the streets are depicted as either perpendicular or parallel lines. The equation of the lane passing through A and B is -7x + 3y = -21.5. What is the equation of the central street PQ?
A) -3x + 4y = 3
B) -1.5x − 3.5y = -31.5
C) 2x + y = 20
D) -2.25x + y = -9.75
