What is the distance between A(-8, 4) and B(4, -1)?
Anettt [7]

Answer:

The distance between A(-8, 4) and B(4, -1) is 13 units.

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula given by:

\displaystyle d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2

We have the two points A(-8, 4) and B(4, -1). Let A(-8, 4) be (<em>x₁, y₁</em>) and let B(4, -1) be (<em>x₂, y₂</em>). Substitute:

d=\sqrt{(4-(-8))^2+(-1-4)^2}

Evaluate:

d=\sqrt{(12)^2+(-5)^2}

So:

d=\sqrt{144+25}=\sqrt{169}=13\text{ units}

The distance between A(-8, 4) and B(4, -1) is 13 units.
