# Math Help - coordinates that trisect a line segment

1. ## coordinates that trisect a line segment

this question I don't have much work to show. :

IF A is (3,6,8) and B is (6,0,-1). Find the points that trisect the line segment.

I thought I would do A+B(1/3) and A+B(2/3) didn't work correctly though. the correct answer is (4,4,5) and (5,2,2).
