Answer 1

Check the picture below.

`~~~~~~~~~~~~\textit{distance between 2 points} \\\\ P(\stackrel{x_1}{2}~,~\stackrel{y_1}{7})\qquad Q(\stackrel{x_2}{4}~,~\stackrel{y_2}{14})\qquad \qquad d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ PQ=√((~~4 - 2~~)^2 + (~~14 - 7~~)^2) \implies PQ=√(( 2 )^2 + ( 7 )^2) \\\\\\ PQ=√( 4 + 49 ) \implies PQ=√( 53 )\implies PQ\approx 7.3`
