vertical
horizontal

Explanation:

The slope of a line is defined as the ratio of the vertical change to the horizontal change between two points on the line ($m=\frac{\Delta y}{\Delta x}$). When the slope $m
ightarrow0$, it means there is no vertical change ($\Delta y = 0$) for a non - zero horizontal change. A line with no vertical change is a horizontal line. A vertical line has an undefined slope ($m=\frac{\Delta y}{\Delta x}$ where $\Delta x = 0$).

Answer:

horizontal
