A city planner is rerouting traffic in order to work on a stretch of road. The equation of the path of the old route can be desc
ribed as y = two fifthsx − 4. What should the equation of the new route be if it is to be perpendicular to the old route and will go through point (P, Q)? y − Q = negative five halves(x − P) y − Q = two fifths(x − P) y − P = negative five halvesx − Q) y − P = two fifths(x − Q)
