Question 1194148: In order to rent books conveniently, you decide to buy a
monthly pass. The pass costs $10, then $1 for each book you
rent. Write an equation in slope-intercept modeling this
situation, then use it to find the total cost if you rent 15 books.

x = number of books rented
Each book costs $1 to rent, so this is the extra cost on top of the $10 pass.
The total cost would be x+10 dollars.
The equation is y = x+10 where y is the total cost.
It is of the form y = mx+b aka slope-intercept form
m = 1 = slope
b = 10 = y intercept
The slope is the extra cost per book rented
The y intercept is the starting cost. It's the amount paid even if you rented 0 books.
Plug in x = 15 to find the value of y
y = x+10
y = 15+10
y = 25
It costs $25 if you rented 15 books.
