Freddy reads an equal number of pages of a book every week. The graph below shows the number of pages of the book left to read, y, after x weeks:



Which equation best models the relationship between x and y? (1 point)


y = –5x + 40

y = –40x + 280

y = –40x + 200

y = –5x + 200

(0,200)(1,160)
slope = (160 - 200) / (1 - 0) = -40
u have a y int (where the line crosses the y axis) at (0,200)

in y = mx + b form, the slope is in the m position and the y int is in the b position...
so ur equation is : y = -40x + 200
