Answer:
No slope
Step-by-step explanation:
The slope of a line or segment in the Cartesian plane is zero if from left to right the value on the y-axis increases, and negative if from left to right the value on the y-axis decreases. So in this case the line is neither positive nor negative.
A slope is zero if the line is horizontal, and because the line in the figure is vertical, its slope is not zero.
For vertical lines in the plane it is said that they have no slope or that it is undefined.
