1.) what is the length of the line segment whose endpoints are (1,1) and (3,3)?
2.) what are the coordinates of the midpoint of the line segment whose endpoints are (c,0) and (0,d)?

Geometry 
Reiny,
given two points (a,b) and (c,d)
length= √[ (ac)^2 + (bd)^2 ]
midpoint = ( (a+c)/2 , (b+d)/2 ) 
Geometry 
Taylor,
I know the formulas, but I'm not sure what the answer would be. Can you please tell me?

Determine the coordinates of the midpoint of the line segment with endpoints C (  4,6 ) and D (  4,  3 )
