A horizontal line is a line perpendicular to the vertical.
A vertical line at 90 degrees
The line x = -4 is vertical, so a line that is perpendicular to it is horizontal, so its slope is 0.
Yes, but only if they are exactly vertical and exactly horizontal (90 degrees angular difference). For real-world examples, many vertical lines can be perpendicular to a single "horizontal" curved line at the points of intersection.

The horizon runs horizontal. Perpendicular to that is VERTICAL.
A horizontal line is a line perpendicular to the vertical.
A horizontal line is perpendicular to a vertical line.
A line which divides a body into two parts, such that each part is the mirror image of the others, then the line is called a line of symmetry. If such a line is parallel to the horizontal plane, then it is called a horizontal line of symmetry. Else, if the line of symmetry is perpendicular to the horizontal plane then it is a vertical line of symmetry.
A vertical line at 90 degrees
'altitude' or perpendicular. If on line is the base (horizontal) line, then the line that is a 90 degrees to it is the perpendicular/altitude.
It is a vertical line touching a horizontal line
A perpendicular line is one that is at right angle to another - usually to a horizontal line. A perpendicular bisector is a line which is perpendicular to the line segment joining two identified points and which divides that segment in two.
The symbol for perpendicular is a straight vertical line resting on a horizontal line just like a 'T' which is upside down.∟ or ┴

No, the horizon is horizontal. A vertical line is perpendicular to the horizon.
