Given two points (-4,-6) and (2,-8):
a. Calculate the distance between them.
d+=+sqrt%28diffy%5E2+%2B+diffx%5E2%29
eg, for (4,6) and (-3,2):
diffy = 6-2 = 4
diffx = -3-4 = -7
-----
d+=+sqrt%284%5E2+%2B+7%5E2%29+=+sqrt%2865%29%29
============================
b. Find the midpoint between them.
It's the average of x & y separately.
eg, for (4,6) and (-3,2):
For x: (4-3)/2 = 1/2
For y: (6-2)/2 = 2
--> (1/2,2)
