see the explanation
Explanation:
Let
s ----> the number of students on the trip
t ----> the number of teachers on the trip
we have the equation

This linear equation represent a proportional relationship, because the line passes through the origin
The constant of proportionality is equal to the slope of the line
so

That means -----> there are a ratio of 25 students by teacher in the trip
or
The number of students is 25 times the number of teachers in the trip
