Question 734959: I have to find the endpoint and length of a line segment but our teacher didn't teach us endpoint! Could you explain it?
Answer by josmiceli(19441)   (Show Source):
You can put this solution on YOUR website! You just need the formula
If the endpoints are ( x1,y1) and (x2,y2)
Then the distance between them is:
--------------
It's important to understand that it doesn't really
matter which point you call (x1,y1) and (x2,y2)
( you can switch the 1's and 2's and the formula
will give you the same answer.
-----------------
If you knew the slope of the line segment and  ,
and 1 of the endpoints, you could find the other endpoint.
-----------------
If you knew everything but one of the coordinates, like
x1, or x2, or y1, or y2, then you can find it.
Hope this helps
