![\bf \textit{distance between 2 points}\\ \quad \\ \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) X&({{ 2}}\quad ,&{{ -3}})\quad % (c,d) Y&({{ -1}}\quad ,&{{2}}) \end{array}\qquad % distance value d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2} \\\\\\ XY=\sqrt{[-1-2]^2+[2-(-3)]^2}\implies XY=\sqrt{(-1-2)^2+(2+3)^2} \\\\\\ XY=\sqrt{(-3)^2+5^2}\implies XY=\sqrt{34}](/tpl/images/0062/8921/8b691.png)
