Aim: To find the coordinates of a general point on x-axis and y- axis by an activity method.

Material Required: Graph Paper, Geometry box,Pencil ,Ruler

Procedure:

1) On a graph paper, draw coordinate axes and label the x-axis as X'OX and y-axis as YOY'.

2) Take 8 points on x-axis and write their coordinates.

3) Observe the coordinates and write the coordinate of any general point on x- axis.

4) Similarly take 8 points on the y-axis and repeat the procedure explained above.

5. Write the conclusion.

Observation :

**A( 1,0)**

__Pt. on x- axis__

B(2,0)

C(3,0)

D(4,0)

E(-1,0)

F(-2,0)

G(-3,0)

H(-4,0)

__Pt. on y- axis__

I(0,1)

J(0,2)

K(0,3)

L(0,4)

M(0,-1)

N(0,-2)

Q(0,-3)

P(0,-4)

Result:

1) Any general point on x-axis is of the form (x, 0).

2) Any general point on y-axis is of the form (0, y).
