Question

Which of the line below has slope of zero

Answer 1

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 2

Horizontal line.

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"
