Question

What is the length of VW?

Answer 1

Answer:

D

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

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

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

      = $\sqrt{(-2)^2+(-4)^2}$

      = $\sqrt{4+16}$

      = $\sqrt{20}$ → D
