Recall that the standard form of the equation of a vertical line is:
[tex]x+0y=C,[/tex]
where C is a constant equal to the x-entry of all the points on the line.
In this case,
[tex]C=-1.[/tex]
Therefore, the equation that represents the vertical line that passes through (-1,0) is
[tex]x+0y=-1.[/tex]
Answer:
[tex]x+0y=-1.[/tex]
