Question

Find the distance between the pair of coordinates: (-4, -3) and (-8, 7). A 10.77 B 3.74 C 04 D 12.65 Question​

Answer 1

`~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-4}~,~\stackrel{y_1}{-3})\qquad (\stackrel{x_2}{-8}~,~\stackrel{y_2}{7})\qquad \qquad d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ d=√([-8 - (-4)]^2 + [7 - (-3)]^2)\implies d=√((-8+4)^2 + (7+3)^2) \\\\\\ d=√((-4)^2 + 10^2)\implies d=√(116)\implies d\approx 10.77`
