2. Repeat #1 for your other system.
3. Compare your two systems. How are they similar? How are they different? Who uses each? Is one preferred over the other in a given situation?
4. Describe the reference structure from which points in the Cartesian coordinate plane are named.
5. Compare the Cartesian coordinate system to the two systems you investigated. Similarities? Differences?
