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

The key features of the graph include the fact the graphs are periodic.
<h3>How to illustrate the graph?</h3>
It should be noted that a graph is a diagram that represents ban interrelations between variables.
The tan graph is simply the visual representation of the tangent function for a range of angles.
In this case, the graphs have been attached and it can be seen that the tan graph repeats every 180° and is not a continuous curve.
