CD has an endpoint at (2,-1)and a midpoint at (8,3). which measure is closest to the length of CD?
Answered by Steve
the distance from end to end is twice the distance from midpoint to end.

That should get you started. I assume you know how to get the distance between two points. . .
Answered by Alicia
do I use the distance formula
Answered by Steve
that would be a good guess, if you want to find the distance, eh?
