Step-by-step explanation:
Let
t -----> the number of hours the job takes
C(t) -----> the total cost for the service
we have

This is the equation of a line in slope intercept form
where
The slope m is equal to 
The y-intercept is the point (0,95) ---> The cost is $95 for the value of t equal zero (fee)
therefore
<u><em>The statements that are true</em></u>
1 a house call fee costs $95
2 the plumber charges $125 per hour
3 the number of hours the job takes is represented by t
