~~~~~~~~~~~~\textit{distance between 2 points} \\\\ R(\stackrel{x_1}{-2}~,~\stackrel{y_1}{-4})\qquad S(\stackrel{x_2}{-8}~,~\stackrel{y_2}{-6})\qquad \qquad d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ RS=√([-8 - (-2)]^2 + [-6 - (-4)]^2)\implies RS=√((-8+2)^2+(-6+4)^2) \\\\\\ RS=√((-6)^2+(-2)^2)\implies RS=√(40)\implies RS\approx 6.3
