$\large \textit{distance between 2 points}\ \quad \
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\
&(-4\quad ,&6)\quad &(8\quad ,&-12)
\end{array}\qquad 
d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}

It only cost like $1.99 at walmart

anonymous · Answer

I am aware of how much one is.

jdoe0001 · Answer

$1.99 for a ruler?   I can find it cheaper than that
for $1.99 they must make some profit I'd think, I mean, they paid about 25cents

d = sq rt (x2 - x1)^2 + (y2 - y1)^2
d = sq rt (8 - (-4)^2 + (-12 - 6)^2
d = sq rt (8 + 4)^2 + (-18^2)
d = sq rt 144 + 324
d = sq rt 468
d = 21.633 rounds to 21.63
