Answer:

750 Books Per Year

Step-by-step explanation:

For this problem, we will be using the standard Rate Of Change formula that we use for graphs:

RoC = (y2 - y1) / (x2 - x1)

y = books

x = year

By plugging in the given values:

RoC = (19000 - 16000) / (1999 -1995)

RoC = 3000 / 4

RoC = 750
