Question

Find the distance between two ponts if x is -7 and y is 4 and x is 5 and y is -7

Answer 1

`\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-7}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-7})\qquad \qquad d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ d = √([5-(-7)]^2+[-7-4]^2)\implies d=√((5+7)^2+(-7-4)^2) \\\\\\ d=√(12^2+(-11)^2)\implies d = √(144+121)\implies d = √(265)\implies d\approx 16.28`
