A line that extends infinitely in both upward and downward directions is called a vertical line. It is typically represented in a coordinate system by an equation of the form (x = a), where (a) is a constant. Vertical lines have an undefined slope and run parallel to the y-axis.
When a line extends infinitely in both upward and downward directions, it is referred to as a vertical line. In a Cartesian coordinate system, a vertical line has an undefined slope and is represented by an equation of the form (x = k), where (k) is a constant.
A line is related to a surface as a point to a plane. In geometry, a point has no dimensions and defines a location in space, while a plane is a two-dimensional surface that extends infinitely in all directions. Similarly, a line is a one-dimensional figure that extends infinitely in two opposite directions, while a surface is a two-dimensional figure that extends infinitely in all directions.
A Line
up and down it is the y axis on a graph
A ray starts at a point and extends forever in ONE direction. A line starts at a point and extends forever in TWO directions.
It extends in both directions (up and down) such that it is parallel to the y-axis.

x = 1 is a graph of a straight line that touches the x-axis at 1 and extends infinitely up and down.

Two. If it were more than two it wouldn't be a line.
