Find the Distance Between Two Points (3,-2) and (-4,5)

$(3, - 2)$ and $(- 4, 5)$

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.

$\sqrt{{((- 4) - 3)}^{2} + {(5 - (- 2))}^{2}}$

Simplify.

Subtract $3$ from $- 4$ .

$\sqrt{{(- 7)}^{2} + {(5 - (- 2))}^{2}}$

Raise $- 7$ to the power of $2$ .

$\sqrt{49 + {(5 - (- 2))}^{2}}$

Multiply $- 1$ by $- 2$ .

$\sqrt{49 + {(5 + 2)}^{2}}$

Add $5$ and $2$ .

$\sqrt{49 + 7^{2}}$

Raise $7$ to the power of $2$ .

$\sqrt{49 + 49}$

Add $49$ and $49$ .

$\sqrt{98}$

Rewrite $98$ as $7^{2} \cdot 2$ .

Factor $49$ out of $98$ .

$\sqrt{49 (2)}$

Rewrite $49$ as $7^{2}$ .

$\sqrt{7^{2} \cdot 2}$

Pull terms out from under the radical.

$7 \sqrt{2}$

The result can be shown in multiple forms.

Exact Form:

$7 \sqrt{2}$

Decimal Form:

$9.89949493 \dots$
