What would a system of coordinates be like if we did not have negative numbers? Would this system allow us to locate all the points on a \(2\)-D plane?
 
Answer:
 
, such a system would us to located all the points on a \(2\)-D plane. We need numbers to represent points to the left of the \(y\)-axis and below the \(x\)-axis. Without numbers, we could locate only the points in the first quadrant and on the positive parts of the axes.
