![\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-\sqrt{5}}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{\sqrt{7}})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[0-(-\sqrt{5})]^2+[\sqrt{7}-0]^2}\implies d = \sqrt{(0+\sqrt{5})^2+(\sqrt{7}-0)^2} \\\\\\ d = \sqrt{(\sqrt{5})^2+(\sqrt{7})^2}\implies d = \sqrt{5+7}\implies d = \sqrt{12}\implies d \approx 3.464](/tpl/images/0384/0789/033bb.png)
