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
