Given :
m=1/2 and the point on the line is (0,0).
The equation of the line is
where m is slope and b is y itercept.
The y-intercept is the point where the lie crosses the y-axis.
(0,0) is the y-intercepet point.
we get b=0.
Substitute m=1/2 and b=0 in the line equation, we get
The line equation is
Similarly, replacing m=-1/-2 and b=0 in the line equation, we get
Set x=0, we get
We get the point (0,0).
Set x=2, we get
We get the point (2,1).
Set x=-2, we get
We get the point (-2,-1).
Mark th epoints (0,0), (2,1) and (-2,-1).
Join all the points by ray.
we get the same line.
Hence we get that
