"What is the slope of the line that passes through the points (2, -1) and (2,0)?"

(2,-1),(2,0)

y2 - y1
-------- = slope
x2 - x1

0 - (-1)
--------- {substituted into slope formula}
2 - 2

1
--- {subtracted}
0

= undefined {it is impossible to divide a number by 0}


The slope is "undefined". Also, this would be a vertical line. Horizontal lines have slopes of 0, such as 0/3.
