Take the number of books to be values of the x-coordinate.
Start at the origin and travel the necessary distance to the left or the right then move up or down in the vertical direction to mark the y-coordinate.
The corresponding cost to be the values of the y-coordinate. Mark or plot at the intersection of the two numbers.
