Question

find the distance between the pair of points. (-16, 12) and (-22, -19).

Answer 1

$d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}$
$d = \sqrt{[-22 - (-16)]^{2} + (-19 - 12)^{2}}$
$d = \sqrt{(-22 + 16)^{2} + (-31)^{2}}$
$d = \sqrt{(-6)^{2} + (-31)^{2}}$
$d = \sqrt{36 + 961}$
$d = \sqrt{997}$
$d \approx 31.57$
