Find the Distance Between Two Points (-9,3) and (-7,-4)

$(- 9, 3)$ and $(- 7, - 4)$

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.

$\sqrt{{((- 7) - (- 9))}^{2} + {((- 4) - 3)}^{2}}$

Step 3

Simplify.

Multiply $- 1$ by $- 9$ .

$\sqrt{{(- 7 + 9)}^{2} + {((- 4) - 3)}^{2}}$

Add $- 7$ and $9$ .

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

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

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

Subtract $3$ from $- 4$ .

$\sqrt{4 + {(- 7)}^{2}}$

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

$\sqrt{4 + 49}$

Add $4$ and $49$ .

$\sqrt{53}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$\sqrt{53}$

Decimal Form:

$7.28010988 \dots$
