$(- 5, 8)$ and $(- 3, 1)$

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.

$\sqrt{{((- 3) - (- 5))}^{2} + {(1 - 8)}^{2}}$

Step 3

Step 3.1

Multiply $- 1$ by $- 5$ .

$\sqrt{{(- 3 + 5)}^{2} + {(1 - 8)}^{2}}$

Step 3.2

Add $- 3$ and $5$ .

$\sqrt{2^{2} + {(1 - 8)}^{2}}$

Step 3.3

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

$\sqrt{4 + {(1 - 8)}^{2}}$

Step 3.4

Subtract $8$ from $1$ .

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

Step 3.5

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

$\sqrt{4 + 49}$

Step 3.6

Add $4$ and $49$ .

$\sqrt{53}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$\sqrt{53}$

Decimal Form:
