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

Answer:140 meters
Step-by-step explanation:1km=100m, 1.4km times 100=140
(4.0625/1) * 10000 = 40625/10000. That simplifies to 65/16. The mixed number is 4 1/16
