How do you find the distance between (3,-5), (-3,0)?

$\sqrt{61}$
$\sqrt{{\left({x}_{1} - {x}_{2}\right)}^{2} + {\left({y}_{1} - {y}_{2}\right)}^{2}}$
$= \sqrt{{\left(\left(3\right) - \left(- 3\right)\right)}^{2} + {\left(\left(- 5\right) - \left(0\right)\right)}^{2}}$
$= \sqrt{{6}^{2} + {5}^{2}}$
$= \sqrt{61}$
