Question 347103
 Detroit road starts in the center of the city, and Lorain road starts 4 miles west of the center of city. Both roads run southwest. If these roads are put on a coordinate plane with the center of the city at (0,0), Lorain Road is represented by the equation y = -x – 4 And Detroit Road is represented by the equation y = - x . How far away is Lorain Road from Detroit road?
----------------------------
Roads with those equations run southeast and northwest, assuming north is the positive y direction.
Ignoring that:
Since the angles with the axes are 45 degs, the distance is 4*sin(45)
= {{{4sqrt(2)/2 = 2sqrt(2)}}}
=~ 2.828 miles
