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= 2/5 x-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) ?
A. y-Q=- 5/2 (x-P)
B. y-Q= 2/5 (x-P)
C. y-P=- 5/2 x-Q)
D. y-P= 2/5 (x-Q)
