Answer:

4 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (- 2, - 4 ) and (x₂, y₂ ) = (- 2, - 8 )

d = $\sqrt{(-2-(-2))^2+(-8-(-4))^2}$

= $\sqrt{(-2+2)^2+(-8+4)^2}$

= $\sqrt{0^2+(-4)^2}$

= $\sqrt{0+16}$

= $\sqrt{16}$

= 4
