You can put this solution on YOUR website!
The x-axis is horizontal.
The y-axis is vertical.
If you connect two points that have the same x value, (4,0) and (4,8) for instance.
The line will be parallel to the y-axis because the x value does not change. Since the lines are parallel, then the line x=4 is also vertical.
