Please make sure to attach the image if it comes with your question.

Given the description I assume that the graph looks something like this
|dw:1729457850127:dw|

If that is right, that means the line is laying horizontally.

Remember there are unique slopes for horizontal and vertical lines:
* Horizontal lines have a slope of zero since y is neither increasing or decreasing.

* Vertical lines have an undefined slope since y is equal to multiple numbers at the same x value.
