Answer 1

`~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{6}~,~\stackrel{y_1}{-8})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{4})\qquad \qquad d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ d=√((~~1 - 6~~)^2 + (~~4 - (-8)~~)^2)\implies d=√((1 -6)^2 + (4 +8)^2) \\\\\\ d=√( (-5)^2 + (12)^2) \implies d=√( 25 + 144)\implies d=√( 169 )\implies d=13`
