Answer:
4 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 2, - 4 ) and (x₂, y₂ ) = (- 2, - 8 )
d = [tex]\sqrt{(-2-(-2))^2+(-8-(-4))^2}[/tex]
= [tex]\sqrt{(-2+2)^2+(-8+4)^2}[/tex]
= [tex]\sqrt{0^2+(-4)^2}[/tex]
= [tex]\sqrt{0+16}[/tex]
= [tex]\sqrt{16}[/tex]
= 4
