Step-by-step explanation:
y=x ................(1)
Let x=0, then y=0
x=1, then y=1
x=-1, then y=-1
x=2, then y=2
(0,0) (1,1) (-1,-1) and (2,2).
y=-x ................(2)
Let x=0, then y=0
x=1, then y=-1
x=-1, then y=-(-1)=1
x=2, then y=-2
(0,0) (1,-1) (-1,1) and (2,-2)
Two lines intersected in the origin.
i.e (0,0).
