Question

how can you find the distance between the pair of points? (-2,-5) and (2,3)

Answer 1

use distance formula ...
simple

Answer 2

\[\in 2D, dist = \sqrt((x1 - x2)^2 + (y1 - y2)^2)\]

Answer 3

so the answer is 4 (square root) of 5, right?
(my keyboard does not have the symbols)

Answer 4

neither does ours
we use the equation editor below
its fun
\[\sqrt{(-2-2)^2+(-5-3)^2}=\sqrt{(-4)^2+(-8)^2)}=\sqrt{16+64}=\sqrt{80}=\sqrt{16*5}=\sqrt{16}\sqrt{5}\]
\[=4\sqrt{5}\]
