City Coordinates Hotel

Stadium (-4000,2000); Overseas Chinese Hotel (-3000,-2000); Baijia Supermarket (2000, -3000)

Examination analysis: firstly, take the railway station as the origin, and the directions of due east and north are the positive directions of X axis and Y axis, and then establish a plane rectangular coordinate system, and then write out the coordinates of each point.

Take the railway station as the origin, and the due east and north directions are the positive directions of the X axis and the Y axis, and establish a plane rectangular coordinate system as shown in the figure:

Stadium (-4000,2000); Overseas Chinese Hotel (-3000,-2000); Baijia Supermarket (2000, -3000).

Comments: The key to solving the problem is to master the one-to-one correspondence between the midpoint of the plane rectangular coordinate system and the ordered real number.
