\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\ \begin{array}{ccccccccc} &&x_1&&y_1&&x_2&&y_2\\ % (a,b) &&(~ 0 &,& -11~) % (c,d) &&(~ -9 &,& -12~) \end{array} \\\\\\ d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ d=√([-9-0]^2+[-12-(-11)]^2) \\\\\\ d=√((-9-0)^2+(-12+11)^2) \\\\\\ d=√((-9)^2+(-1)^2)\implies d=√(82)
