...system can be made to cope with points involving negative coordinates, such as (−2, 3) or (−2, −3). Just as a number line can be extended to deal with negative numbers, the x-axis and y-axis can be extended to deal with negative coordinates. In this way, if a point is to the left of the origin, its x-coordinate is negative, and if it is below the origin, its...
