Find the Distance Between Two Points (0,0) and (3,-4)

$(0, 0)$ and $(3, - 4)$

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.

$\sqrt{{(3 - 0)}^{2} + {((- 4) - 0)}^{2}}$

Simplify.

Subtract $0$ from $3$ .

$\sqrt{3^{2} + {((- 4) - 0)}^{2}}$

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

$\sqrt{9 + {((- 4) - 0)}^{2}}$

Subtract $0$ from $- 4$ .

$\sqrt{9 + {(- 4)}^{2}}$

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.
