4 10 ¢
6 15 ¢
8 20 ¢
y = mx + c
=> 0 = 0 + c
=> c = 0
=> y = mx
=> 5 = m(2)
=> m = 5/2
=> y = 5x /2
Lets check all other
x = 4 => y = 5 * 4 /2 = 10
x = 6 => y = 5 * 6 /2 = 15
x = 8 => y = 5 * 8 / 2 = 20
hence y = 5x
y = fine
x = Days over due
Hence correct statement is
y = five-halves x, where y is the cost in cents for a book that is x days overdue
