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?
OA. -3x+4y=3
O B. 3x+7y=63
OC. 2x+y=20
O D. 7x+3y= 70
