loris [4]

The measure of the segment DF is 2 2/3

<h3>Segment  Addition postulate</h3>

The segment addition postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

A line is a distance between two points. From the given line;

DF = F - D

Given the following

F = -1 1/3
D = -4

Substitute

DF = -1 1/3 - (-4)

DF = 4 - 4/3

DF = 8/3

DF =2 2/3

Hence the measure of the segment DF is 2 2/3
