Answer:
Option C 

Explanation:
we know that
The initial value is the value of the function when the value of x is equal to zero
The initial value is the y-intercept of the function
In this problem we have
 -----> equation of the line into slope intercept form
 -----> equation of the line into slope intercept form
therefore
 -----> the slope
 -----> the slope
 ----> the y-intercept
 ----> the y-intercept
The initial value is
