Question 218351
The endpoints of segment LF are L(-2,2) and F(3,1). The endpoints of segment JR are J(1,-1) and R(2,-3). What is the approximate difference in the lengths of the two segments? 
--------------
Distance = sqrt(diffy^2 + diffx^2)
For LF:
{{{s = sqrt((-2-3)^2 + (2-1)^2)}}}
{{{s = sqrt(25 + 1)}}}
{{{s = sqrt(26)}}}
s = ~ 5.099
------------
Find the length of JR the same way, then find the difference.
