Question

Draw the graph of linear equations $y=x$ and $y=x+1$ on the same Cartesian plane. What do you observe?

Answer 1

$y=x$ and $y=x+1$

find the nectar of graph

$y=k$ [it is straight line passing through the origin

$y=x+1$

put $y=0,y=1,$ and $y=2$

$x=-1,x=0.$and $x=1$

x	-1	0	1
y	0	1	2

It is parallel to each other it has no solution.
