Question

Find the distance between the points (-6, -1) and (-6, 11).
​

Answer 1

$\sqrt{(x2} - x1) {}^{2} + (y2 - y1) {}^{2}$

$\sqrt{( - 6 + (6) {}^{2} } + (11 - ( - 1) {}^{2}$

$\sqrt{( - 6 + 6) { }^{2} } + (11 + 1) {}^{2}$

$\sqrt{(0) {}^{2} } + (12) {}^{2}$

$\sqrt{(0) { }^{2} } + (12) {}^{2}$

$\sqrt{0 + 144}$

$\sqrt{144}$

$12$
