5/0 UNDEFINED... The answer is a vertical line.
To figure the slope of a line, you can either use [tex] \frac{rise}{run} [/tex] or [tex]m = \frac{y2 - y1}{x2 - x1} [/tex]. Remember, 'm' represents the slope of the line.

We can use the point (12, 10) as (x1, y1) and the point (12, 5) as (y1, y2):

[tex]m = \frac{5 - 10}{12 - 12} [/tex]

[tex]m = \frac{-5}{0} [/tex]

[tex]m = 0[/tex]

So, the answer is 0, which means the slope is undefined.
