It is a function. If the graph contains at least two points on the same vertical line, then it is not a function. This is called the vertical line test.
A line that is at right angles to a vertical line is said to be horizontal.
There is only one set of perpendicular lines in a right triangle; the horizontal line and the vertical line that make it 90 degrees.
The slope of a vertical line is undefined. Horizontal slope is 0.
A vertical line.

The vertical line is the Prime Meridian.
Geographers call the 0 degree line of longitude the Prime Meridian. This line is designated where the longitude values are defined as 0 degrees, dividing the Earth into Eastern and Western hemispheres. The Prime Meridian runs through Greenwich, London, UK.
A vertical line is 180 degrees.
A vertical line at 90 degrees

Geographers call the 0-degree line of longitude the Prime Meridian. This line runs through Greenwich, England and serves as the starting point for measuring longitude.
because 360 degrees is the total amount of degrees you can get. the degrees are essentially the angle measurement. anything that is 180 degrees is a vertical. so vertical angels are used to indicated a 180degree line.
A line 90 degrees from horizontal is a plumb line.
