PLZ HELP MEH IN A TESTT 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 described 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)
