The  x-component of the line segment connecting the points  (3,2)  and  (-2,1)  is
dx = (-2) - 3 = -5.

The  y-component of this line segment is
1 - 2 = -1.

Now,  the length of this line segment is
sqrt%28dx%5E2+%2B+dy%5E2%29 = sqrt%28%28-5%29%5E2+%2B+%28-1%29%5E2%29 = sqrt%2825+%2B+1%29 = sqrt%2826%29 = 5.099 (approximately).
