D5: Working with Coordinates

Use the map below to learn more about Cartesian Coordinates.

Click on the map below to create a marker. You can read the coordinates of the marker by clicking on it. The X-coordinate measures the East-West distance, while the Y-coordinate measures the North-South distance. Can you figure out where the origin (0,0) of this coordinate system is located?

Some of the coordinates are negative. What part of Washington would have negative X and Y coordinates? Would the White House have either a negative X or Y coordinate?
