Find the Distance Between Two Points (0,4) , (-4,6)

$(0, 4)$ , $(- 4, 6)$

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.

$\sqrt{{((- 4) - 0)}^{2} + {(6 - 4)}^{2}}$

Step 3

Simplify.

Subtract $0$ from $- 4$ .

$\sqrt{{(- 4)}^{2} + {(6 - 4)}^{2}}$

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

$\sqrt{16 + {(6 - 4)}^{2}}$

Subtract $4$ from $6$ .

$\sqrt{16 + 2^{2}}$

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

$\sqrt{16 + 4}$

Add $16$ and $4$ .

$\sqrt{20}$

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:

$4.47213595 \dots$
