Find the Distance Between Two Points (-8,-2) and (-6,2)

$(- 8, - 2)$ and $(- 6, 2)$

Step 1

Use the distance formula to determine the distance between the two points.

$Distance = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}}$

Step 2

Substitute the actual values of the points into the distance formula.

$\sqrt{{((- 6) - (- 8))}^{2} + {(2 - (- 2))}^{2}}$

Step 3

Simplify.

Multiply $- 1$ by $- 8$ .

$\sqrt{{(- 6 + 8)}^{2} + {(2 - (- 2))}^{2}}$

Add $- 6$ and $8$ .

$\sqrt{2^{2} + {(2 - (- 2))}^{2}}$

Raise $2$ to the power of $2$ .

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

Multiply $- 1$ by $- 2$ .

$\sqrt{4 + {(2 + 2)}^{2}}$

Add $2$ and $2$ .

$\sqrt{4 + 4^{2}}$

Raise $4$ to the power of $2$ .

$\sqrt{4 + 16}$

Add $4$ and $16$ .

$\sqrt{20}$

Rewrite $20$ as $2^{2} \cdot 5$ .

Factor $4$ out of $20$ .

$\sqrt{4 (5)}$

Rewrite $4$ as $2^{2}$ .

$\sqrt{2^{2} \cdot 5}$

Pull terms out from under the radical.

$2 \sqrt{5}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$2 \sqrt{5}$

Decimal Form:

$4.47213595 \dots$
