Question 165822
the distance between (-12,7) and (10,-3)
----------------------
The distance between 2 points is the sqrt of the (difference in x)^2 + the (difference in y)^2.

= {{{sqrt(22)^2+(10)^2]]]
= {{{sqrt(484 + 100)}}}
= {{{sqrt(584)}}}
= {{{2sqrt(146)}}}
Only the differences matter, not the signs, since it's squared.
