Answer
Passion is less than or equal to intimacy, (or: intimacy is more than or equal to passion).
Work Step by Step
The red graph (passion) and the blue graph (intimacy)
intersect at x=5 (passion equals intimacy there), and for x between 5 and 7 (for $ x\in(5,7)$), the intimacy graph is above the passion graph.
So for $ x\in[5,7)$, passion is less than or equal to intimacy, (or: intimacy is more than or equal to passion).
