Question

Find the distance between each pair of points. Round youranswer to the nearest tenth, if necessary.(4,2), (-6,-6)

Answer 1

the distance between two points is found:

$\begin{gathered} d=\sqrt[]{(x2-x1)^2+(y2-y1)^2} \\ d=\sqrt[]{(-6-4)^2+(-6-2)^2} \\ d=\sqrt[]{(-10)^2+(-8)^2} \\ d=\sqrt[]{100+64} \\ d=\sqrt[]{164} \\ d=12.8 \end{gathered}$

answer: distance = 12.8
