Question

on a graph paper dtaw a line parallel to X axis and Y axis write a coordinates of four points on the line. written how eqations of line can be obtained from coordinate​

Answer 1

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
