Vertical lines have the same x coordinate and the formula for a slope is y2-y1 divided by x2-x1
Let's just say, for example, that the x value is 7.
7-7=0
So, if the x values are the same, the denominator of the fraction becomes zero.
And, mathematically speaking, a fraction with a denominator of zero doesn't exist.

Step-by-step explanation:
Vertical lines have the same x coordinates
The slope is given by
m = (y2-y1) / (x2-x1)
The x values are the same
m = (y2-y1) / (x-x)
m = (y2-y1) / 0
Any number, except 0, divided by 0 is undefined
