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

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

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.

Subtract $2$ from $8$ .

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

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.

$10$
