Question

1. On a graph paper, draw a line parallel to the X-axis or Y-axis. Write coordinates
of any four points on the line. Write how the equation of the line can be obtained
from the coordinates.
[Instead of parallel lines, lines passing through the origin or intersecting the
X or Y- axis can also be considered]
​

Answer 1

On a graph paper, draw a line parsllel to the X-axisorY-axis.Write coordinate of any four points on the line, Write how thw equations of the line can be obtained from the coordinates.

[Intead of parallel lines, lines pssing through the origin or intersecting XorY-axis can also be considered]

Answer

Four points are (1,2), (1,1), (1,0), (1,−1) on the line

Now equation of line between (1,0) & (1,1)

y−0=

0

1

(x−1)

x=1

Now equation of line between (1,2) & (1,−1)

y−2=

0

−1−2

(x−1)

x=1
