Question

the distance between the points ( 2, -1, -8) and ( 6, -3. 4) is

Answer 1

Use the distance formula
s = sqrt ((x2 - x1)^2 + (y2 - y1)^2) where (x1 , y1) and (x2 , y2) are the endpoints of the length of line

Answer 2

\[d=\sqrt{(x_o-x_1)^2+(y_o-y_1)^2+...+(n_o-n_1)^2}~:~for ~"n"~elements\]

Answer 3

to avoid having to keep track of stuff, i just move the points so one of them is at the origin; then square add sqrt
