26 minutes ago, I gave you a complete solution for the distance
between (-1, 2) and (7, 8). As I wrote it, I gave you a complete
explanation of every step, so that you would then know how to
find the distance between ANY two points.
Go back and review that one. Then use the same procedure to solve
this one. When you're finished, you'll have the solution to this one ...
completely on your own ... and plus, you'll LEARN something too.
