If you dont have slope then you cant tell

An undefined slope is vertical.

The equation of a line with an undefined slope is x = a.

Undefined slope is when a line is exactly on the y-axis, for reasons unknown, the slope of a line on the y-axis cannot be determined, so therefore it it "undefined." A line with no slope is a line with a slope of zero. In order for a line to have a slope of zero, it must be directly on the x-axis, meaning it is horizontal. Horizontal lines are straight and have no slope

The slope of a vertical line is undefined. Horizontal slope is 0.
