Find the Distance Between Two Points What is the distance between the points (3,5) and (6,9) ?

What is the distance between the points $(3, 5)$ and $(6, 9)$ ?

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

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

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

$\sqrt{{(6 - 3)}^{2} + {(9 - 5)}^{2}}$

Simplify.

Subtract $3$ from $6$ .

$\sqrt{3^{2} + {(9 - 5)}^{2}}$

Raise $3$ to the power of $2$ .

$\sqrt{9 + {(9 - 5)}^{2}}$

Subtract $5$ from $9$ .

$\sqrt{9 + 4^{2}}$

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

$\sqrt{9 + 16}$

Add $9$ and $16$ .

$\sqrt{25}$

Rewrite $25$ as $5^{2}$ .

$\sqrt{5^{2}}$

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