Question

Does anyone know which one it is ?

Answer 1

Answer:

The slope of the line is undefined

Step-by-step explanation:

The given line is a vertical line.

The slope of any vertical line is undefined.

Let us see why by using the slope formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

We substitute the coordinates of the points to obtain:

$m = \frac{3 - - 2}{1 - 1} = \frac{5}{0}$

This is not defined.
