Answer:

C

Step-by-step explanation:

Find the distance of AB:

Distance formula: [tex]\sqrt{[(-8)-(-2)]^2+(9-1)^2}[/tex]

[tex]\sqrt{(-6)^2+(8)^2}=\sqrt{36+64}=\sqrt{100}=10 units[/tex]

Find the distance of BC:

Distance formula: [tex]\sqrt{[(-2)-1]^2+[1-(-3)]^2}[/tex]

[tex]\sqrt{(-3)^2+4^2}=\sqrt{9+16} =\sqrt{25} =5 units[/tex]

AB=10 units

BC=5 units

AB:BC = 10:5=2:1
