The given equation is
[tex]x=8[/tex]
This given equation is represented graphically by a vertical line at x = 8
Let us draw it
1) Its domain is
[tex]D=\mleft\lbrace8\mright\rbrace[/tex]
2) Its range is
[tex]R=(-\infty,\infty)[/tex]
3) Its zero is
[tex]x=8[/tex]
4) No y-intercept
5) Slope is undefined
6) Type of the slope: None
7) x = 8 can not be a function, then f(8) does not exist
8) f(x) = 0 does not exist
