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?

In the cartesian plane OXY, we consider the lines with equation ax + 3y + 4=0 and x + 2ay + 7=0 with a as real parameter. Which of the following statements is true?
A. There exist a unique value for a for which the lines are parallel and distinct
B. A unique value of a exists for which the lines are coincident
C. Two values of a exist for which the lines are parallel
D. No value of a for which the lines are parallel
We consider 3 non-aligned points in the plane. How many lines can one find that are
exactly at the same distance from these three points
