Example 1. How will you describe the position
of a table lamp on your study table to another person?

Answer
To describe the position of a table lamp placed on the table, let us consider the table lamp as P and the table as a plane. Thus, the position of the table lamp P is described by the ordered pair (a, b).
Answer:
To describe the position of a table lamp on the study table, we have two take two lines, a perpendicular and horizontal.
Considering the table as a plane and taking the perpendicular line as Y axis and horizontal as X axis.
Take one corner of the table as origin where both X and Yaxes intersect each other.
Now, the length of the table is Y axis and breadth is Xaxis.
From the origin, join the line to the lamp and mark a point.
Calculate the distance of this point from both X and Y axes and then write it in terms of coordinates.
Let the distance of a point from X axis is x and from Y axis is y then the position of the table lamp in terms of coordinates is (x,y).
