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?
The equation of the lane passing through and is
Solve for
Hence
Since the central street is perpendicular to the lane passing through and then
Point
The equation of the central street is
