Question

A distância entre os pontos (-1,0) e (-3,2) é?

Answer 1

Joga na formula de distancia entre pontos:

$D = \sqrt{(xb - xa)^{2}+(yb-ya)^{2}} =\\\\ \sqrt{(-3 - (-1))^{2}+(2-0)^{2}} =\\\\ \sqrt{(-3+1))^{2}+(2)^{2}} =\\\\ \sqrt{(-2))^{2}+(2)^{2}} =\\\\ \sqrt{4+4} => D =\\\\D =\sqrt{8}=\\\\ D = 2\sqrt{2}$
