Question 98769


     determine the length of each line segment. Where appropriate,
round to the nearest hundredth.
( 1,-1) (3,2)

           To find the length of the line segment we use the distance formula  and not pythagorean formula

       length = sq.rt (X-x)^2+(Y-y)^2  where X,Y = 1,-1   and x,y = 3,2

              = sq.rt (1-3)^2+(-1-2)^2

              = sq.rt (-2)^2+(-3)^2
              = sq.rt (4+13)

              = sq.rt (17)

       length to the nearest hundredth = 4.12
