The graph of a hyperbola is shown. what is the length of the transverse axis

The length of the transverse axis is 18 units.
"The transverse axis is a line segment that passes through the center of the hyperbola and has vertices as its endpoints."
Given, the vertices of the hyperbola are at (-9, 0) and (9, 0).
Therefore, the length of the transverse axis is
[tex]= (9+9) units\\= 18 units[/tex]
