Chicago ln Chicago, the road system is set up like a Cartesian plane, where streets are indicated by the number of inlines they are from Madison Street and State Street. For example, Wrigley Field in Chicago is located at 1060 West Addison, which is 10 inlines west of State Street and 36 inlines north of Madison Street. Treat the intersection of Madison Street and State Street as the origin of a coordinate system, with east being the positive $x\text{-axis}$.
