Plot the following points on a graph sheet
(4,0),(3,0),(2,0),(1,0),(0,0),(1,0),(2,0),(3,0),(4,0).
Observing the above graph:
1. All points lie on Xaxis.
2. The common property of all these points is its ycoordinate is zero.
3. The straight line joining all these points may be denoted as y=0.
The ycoordinate on Xaxis is zero. Xaxis may be denoted by the straight line y=o. 
Plot the following points on a graph sheet.
(0,1),(0,2),(0,3,),(0,4),(0,0),(0,1),(0,2),(0,3),(0,4)
Observing the above graph:
1. All these points lie on Yaxis.
2. The common property of all these points is x = o.
3. The xcoordinate of any point on yaxis is zero.
4. We can denote the yaxis as x=0.
The xcoordinate on Yaxis is zero. Yaxis may be denoted by the straight line
x=o. 
Directions: Draw the graph for xaxis and yaxis on a graph paper.
