Answer:

undefined

Step-by-step explanation:

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-4, -2) and (-4, -1).

Substitute:

[tex]m=\dfrac{-1-(-2)}{-4-(-4)}=\dfrac{-1+2}{-4+4}=\dfrac{1}{0}[/tex]

Division by 0 is not possible!

Therefore the slope is undefined.

(-4, -2) (-4, -1)

We have the same x = -4 in the coordinates of the points. Therefore it's a vertical line. Vertical line has undefined slope.
