Answer:
[tex]\huge\boxed{\sf |AB| = 8\ units}[/tex]
Step-by-step explanation:
Given the two co-ordinates:
A(x1,y1) = (-4,-8)
B(x2,y2) = (-4,0)
Putting them in the distance formula:
[tex]|AB| = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\|AB| = \sqrt{(-4-(-4))^2+(0-(-8))^2} \\\\|AB| = \sqrt{(-4+4)^2+(0+8)^2} \\\\|AB| = \sqrt{8^2} \\\\|AB| = 8\ units\\\\\rule[225]{225}{2}[/tex]
Hope this helped!
