(Activity 4)






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 :

Pt. on x- axis

A( 1,0)
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).
