Yes. There is no positive or negative rise to generate a slope, and it cannot have a run of zero length.

The slope of a horizontal line is zero.
the x-axis is the horizontal line which means the slope is 0. any line parallel also has a slope of zero
Although all lines have the relationship that defines slope, one can argue that not all lines do have one. The exception would be vertical lines. Slope is defined as the vertical rate of change divided by the horizontal rate of change. In the case of a vertical line, there is no horizontal rate of change, and calculating slope would cause division by zero. The closest you could come to expressing the slope of a vertical line would be ∞
It would be a undefined slope.There are four types of slope:Postive slope (when lines go uphill from left to right)Negative slope (when lines go downhill from left to right)Zero slope (when lines are horizontal)Undefined slope (when lines are vertical)
The slope of a horizontal line is zero. That's because the slope measures how steep the line is, and a flat line is not steep at all and therefore has no slope.
