Jacqueline reads 25 pages every night. which graph correctly displays y, the total number of pages that jacqueline has read after x days?

The correct answer is) D.  Because on the graph you can see that it increases by 25 each day which follows the equation Y=25x

The reason for this is because she reads 25 pages a night Meaning that the total number of pages Jacqueline has read (Variable Y) = 25 pages a night (x)

y = 25x

In case of 3 days    y = 25x3=75 pages

                  4 days   y =25x4=100 pages
