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)?

given two points (a,b) and (c,d)

length= √[ (a-c)^2 + (b-d)^2 ]
midpoint = ( (a+c)/2 , (b+d)/2 )

I know the formulas, but I'm not sure what the answer would be. Can you please tell me?
