Algebra Examples

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

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.

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

Simplify.

Subtract $1$ from $- 1$ .

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

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

$\sqrt{4 + {((- 8) - (- 3))}^{2}}$

Multiply $- 1$ by $- 3$ .

$\sqrt{4 + {(- 8 + 3)}^{2}}$

Add $- 8$ and $3$ .

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

Raise $- 5$ to the power of $2$ .

$\sqrt{4 + 25}$
