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

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

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.

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

Step 3

Simplify.

Multiply $- 1$ by $- 2$ .

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

Add $- 8$ and $2$ .

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

Raise $- 6$ to the power of $2$ .

$\sqrt{36 + {((- 6) - 2)}^{2}}$

Subtract $2$ from $- 6$ .

$\sqrt{36 + {(- 8)}^{2}}$

Raise $- 8$ to the power of $2$ .

$\sqrt{36 + 64}$

Add $36$ and $64$ .

$\sqrt{100}$

Rewrite $100$ as $10^{2}$ .

$\sqrt{10^{2}}$

Pull terms out from under the radical, assuming positive real numbers.

$10$
