Question

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 = 2/5x − 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 (Q, P)?

y − Q = -5/2(x − P)
y − Q = 2/5(x − P)
y − P = -5/2(x − Q)
y − P = 2/5(x − Q)

ik its not b or d

Answer 2

please help this is time sensitive

Answer 3

Answer 4

oop-

Answer 5

i forgot how to do that lol

Answer 6

The slopes of two perpendicular lines multiply to give you -1

So I can see why you would eliminate B and D

Answer 7

The point (Q, P) is in the form of (x, y)

so you subtract Q from x
and you would subtract P from y

Answer 8

and that's how you would get a line that's perpendicular and goes through the point

Answer 9

so C?

Answer 10

That's correct!
