A
coordinate is the position of an object in a , relative to the corresponding axis. In a coordinate system, are usually expressed as a
coordinate pair, also called
ordered pair, which is denoted by
(x,y).
The first coordinate states the position along the
x-axis and the second coordinate states the position along the
y-axis. In a coordinate system, three are needed to express a coordinate position. Each number tells the point's position in relation to one axis.
A coordinate point in three dimensions is also referred to as an
ordered triple and denoted by
(x,y,z). The same reasoning applies for coordinate systems with more than three dimensions.
