Find the length of a line segment with endpoints of 19 and –39. A.–58 B.–20 C.20 D.58

I'm really thinking it's C, because i know that a length cannot be a negative number!! Any suggestions?? *^.^*

OpenStudy (***[isuru]***):

nope... think of it as 2 endpoints in a Cartesian plane or a number line.. they r asking the length of the number line... so u have to answer how many units does this line is long ... if it was in a graph like this|dw:1392755420458:dw|
