How to determine coordinates of a point?
On a graph paper draw X'OX and YOY'. Here X'OX and YOY’ be the two coordinate axes.
Then mark a point on the graph and name the point as P such that P is at the perpendicular distance of a units from the yaxis and again similarly b units from the xaxis. Then, we denote that the coordinates of P are P(a, b)
From the above discussion, a is called the abscissa or xcoordinate of P and b is called the ordinate or ycoordinate of P.
Examples to get coordinates of a point:
1. In the adjoining figure, to find the coordinate of point P the distance of P from yaxis is 2 units and the distance of P from x axis is 3 units.
Therefore the coordinates of point P are (2, 3).
2. In the adjoining figure, to find the coordinate of point P the distance of P from yaxis is 5 units and the distance of P from x axis is 5 units.
Therefore the coordinates of point P are (5, 5).
3. In the adjoining figure, to find the coordinate of point P the distance of P from yaxis is 7 units and the distance of P from x axis is 4 units.
Therefore the coordinates of point P are (7, 4).
4. In the adjoining figure, to find the coordinate of point P the distance of P from yaxis is 0 units and the distance of P from x axis is 0 units.
Therefore the coordinates of point P are (0, 0).
5. In the adjoining figure, to find the coordinate of point P the distance of P from yaxis is 0 units and the distance of P from x axis is 3 units.
Therefore the coordinates of point P are (0, 3).
6. In the adjoining figure, to find the coordinate of point P the distance of P from yaxis is 6 units and the distance of P from x axis is 0 units.
Therefore the coordinates of point P are (6, 0).
