Using longitude and latitude

Well since many of us love looking at maps (especially your teacher) we now get to do so in math.  We are studying coordinate grids.  Here is a list of mystery cities.  I have given you their longitude and latitude, can you find which cities i'm listing?  Its a lot easier to use a computer for this, but I would like you to use the Atlas to practice working with coordinates on a plane:

We can use N, S, E and W or
we can use + for north and east
                    -- for south and west

1. N13.9167,  E100.6
2. 49.2833 -123.117
3.  33.9333 , -118.4
4. -22.8667 , -43.3667

5. N 45.5, E 12.3333

6. -41.3333, 174.8
