What is the initial value of the equation shown?

y = −7x − 6

a. −13
b. −7
c. −6
d. −1

Option C  

Step-by-step 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

therefore

-----> the slope

----> the y-intercept

The initial value is
