COORDINATES OF A POINT
On the coordinate plane, each point is represented by an ordered
pair P(x,y) in which
x is called x-coordinate or abscissa or first component and
y is called y-coordinate or ordinate or second component.
In an ordered pair, the order is important. Every time x coordinate should be written before
y-coordinate.
The horizontal number line is called x-axis and the vertical number line is called y-axis.
