~~~~~~~~~~~~\textit{distance between 2 points} \\\\ C(\stackrel{x_1}{-5}~,~\stackrel{y_1}{9})\qquad G(\stackrel{x_2}{-2}~,~\stackrel{y_2}{4})\qquad \qquad d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ CG=√([-2 - (-5)]^2 + [4 - 9]^2)\implies CG=√((-2+5)^2+(-5)^2) \\\\\\ CG=√(3^2 +(-5)^2)\implies CG=√(34)
