Answer to Question #205074 in Algebra for rashod

Question

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?

Answer 1

The equation of the lane passing through A and B:

$y=\frac{7}{3}x-21.5/3$

The equation of the central street PQ (perpendicular to AB):

$y=-\frac{3}{7}x-21.5/3$
