Step-by-step explanation:
A equation of a line can be represented by
[tex]y = mx + b[/tex]
Where m is the slope and b is the y intercept.
For Line A, the slope is 0 so our m is 0 and our y intercept is 4 so our equation will be
[tex]y = 0(x) + 4[/tex]
[tex]y = 4[/tex]
For the second equation, qe have no y intercept and a undefined slope so that means that our equation will be in the form of
[tex]x = a[/tex]
where a is the x intercept
7 is the x intercept so our equation is
[tex]x = 8[/tex]
