Answer :
A horizontal line is perfectly flat. It has no "steepness" and neither goes up nor down. Mathematically, we can express that by saying that a horizontal line has a slope of 0
Answer:
Horizontal line.
Step-by-step explanation:
Let's see what a slope is.
The slope is nothing the steepness of a line. We find the slope using two points on the line.
If the slope has zero, then it is horizontal line.
If the slope is infinity, then it is a vertical line.
Therefore, the answer is "horizontal line"
