1:
20 + 12x = y
20 represents the membership fee 
12 represents the cost of each book
x represents the number of books
y represents the total costs of all books and membership cost

2:
30 + 12x = y
30 represents the membership fee 
12 represents the cost of each book
x represents the number of books
y represents the total costs of all books and membership cost

3:
Both functions have different y-intercepts but the same slope
