Answer:
see the explanation
Step-by-step explanation:
Let
y ----> the number of bacteria
x ----> the number of hours
we know that
The y-intercept is the value of y when the value of x is equal to zero
In the context of this problem
The y-intercept is the initial number of bacteria at the begin of the study
The y-intercept is the point (0,125)
therefore
The value of y=125 is the initial number of bacteria at the begin of the study (For x=0)
