Answer:
20 units.
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
[tex]\displaystyle d_2 = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]
Let W(-6, -8) be (x₂, y₂) and X(6, 8) be (x₁, y₁).
Substitute and evaluate:
[tex]\displaystyle \begin{aligned}d & = \sqrt{(-8-8)^2 + (-6-6)^2} \\ \\ & = \sqrt{(-16)^2 + (-12)^2} \\ \\ & = \sqrt{400} \\ \\ & = 20 \end{aligned}[/tex]
Therefore, the distance between the two points is 20 units.
