\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\ \begin{array}{ccccccccc} &&x_1&&y_1&&x_2&&y_2\\ % (a,b) &&(~ -3 &,& -4~) % (c,d) &&(~ -8 &,& 1~) \end{array} \\\\\\ d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ d=√([-8-(-3)]^2+[1-(-4)]^2)\implies d=√((-8+3)^2+(1+4)^2) \\\\\\ d=√((-5)^2+5^2)\implies d=√(50)\implies d=√(25\cdot 2)\implies d=√(5^2\cdot 2) \\\\\\ d=5√(2)
