Answer:
Step-by-step explanation:
Let
x ----> represents the number of subscriptions she sells
f(x) ---->represent her paycheck amount for the week
we know that
The linear function in slope intercept form is equal to
where
m is the slope or unit rate of the linear function
b is the y-intercept or initial value of the linear function
In this problem we have that
The slope is equal to
The y-intercept is equal to
---> value of f(x) when the value of x is equal to zero
substitute
