Neil reads equal numbers of pages of a book every week. The graph shows the number of pages of the book left to read, y, after x weeks:
A graph titled Neil’s Book Reading shows Number of Weeks on the x-axis and Number of Pages Left on the y-axis. The scale on the x-axis shows numbers from 0 to 5 at increments of 1, and the scale on the y-axis shows numbers from 0 to 315 at increments of 45. A straight line joins the ordered pairs 0, 225 and 1, 180 and 2, 135 and 3, 90 and 4, 45 and 5, 0.
Which equation best models the relationship between x and y?
y = −5x + 45
y = −45x + 315
y = −5x + 225
y = −45x + 225
