A straight line.
A constant, a flat line
A horizontal line is a perfectly streight line that has a slope of 0. Ex. ____________________________________________________________ <---example
When a line approaches a horizontal orientation, its slope approaches zero. This means that for any change in the x-axis, there is little to no change in the y-axis, indicating a flat or nearly flat relationship between the two variables. As the line gets closer to being perfectly horizontal, the slope becomes exactly zero, signifying no vertical change regardless of horizontal movement.
Every place that isn't perfectly flat. Which is almost everywhere.
Horizontal lines always have a slope of zero. (i.e completely flat, level surfaces have a slope of zero). However a line does not have to have a slope of zero in order to be a line.

The name of a flat mirror is "plane mirror"
A 'plane' is a perfectly flat surface defined mathematically by three points. A planer is designed to create a perfectly flat surface on wood.
A flat, level surface is a plane.
second space with flat sign. or high a flat is line above fifth line with flat sign
what is wrong with this sentence "the bottom of the ocean is different from land masses because the ocean bottom is perfectly flat."
A flat line in cardiology is called asystole.
The Salar de Uyuni in Bolivia is one of the most level places on Earth, as it is an expansive salt flat that creates a nearly perfectly flat surface. Additionally, parts of the Bonneville Salt Flats in Utah are also known for their level terrain, and are often used for land speed record attempts due to their flatness.
That's usually "quite flat." The palindrome is "level."
A perfectly straight line is 180 degrees.
