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.

<h2>Problem:</h2>

  • What is the distance between A(-8,4) and B(4,-1)

<h2>Given:</h2>

\quad\quad\quad\quad\tt{A.) x\tiny{1}\small{=-8}, y\tiny{1}\small{=4}}

\quad\quad\quad\quad\tt{B.) x\tiny{2}\small{=4}, y\tiny{2}\small{=-1}}

<h2>Formula for distance (d):</h2>

\quad\quad\quad\quad\tt{d =  \sqrt{(x  \tiny{2} \small{ - x \tiny{1} \small {)}^{2} + (y \tiny{2} \small{ - y \tiny{1}  \small{)}^{2} } }}}

<h2>Solution:</h2>

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

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

\quad\quad\quad\quad\tt{d =  \sqrt{  {144}  + {25}}}

\quad\quad\quad\quad\tt{d =  \sqrt{ 169}}

\quad\quad\quad\quad\tt{d =  13}

<h2>So the final answer is:</h2>

\quad\quad\quad\quad\boxed{\boxed{\tt{\color{magenta}d =  13}}}
