Question

1. Two students are reading a novel Ashley reads 10 pages per day. Carly reads 8 pages per day, but she starts early and is already on page 40. Part c

What does the point of intersection of the graph tell you?​

Answer 1

• the y-intercept for Ashley says that at the beginning she read 40 pages already.

• Both line intercepting means, they reached the same amount of pages at day 20.

Explanation:

Let the reading per day be d,

Carly total pages read: 8d + 40

Ashley total pages read: 10d

Here:

8d + 40 = 10d

40 = 10d - 8d

40 = 2d

d = 20

• They will read the same pages at day 20.

• They will have read 200 pages at that point.

• They intersect at coordinates: ( 20, 200 )
