Answer 1

a. The table represents a proportional relationship

b. The constant of proportionality is 5/6

Proportional relationship:

Proportional relationship are relationship between variable where their ratios are equivalent. The variables in our case are total weight(pounds) and number of books.

Therefore, let's check if the table represent a proportional relationship.

let

total weight = x

number of book = y

k = constant of proportionality

y = kx

10 = k12

k = 10 / 12 = 5 / 6

y = kx

15 = 18k

k = 15 / 18

k = 5 / 6

y = kx

25 = 30k

k = 25 / 30

k = 5 / 6

y = kx

50 = k60

k = 50/60 = 5 / 6

The constant of proportionality is the same. Therefore, the table represents a proportional relationship

The constant of proportionality(k) is 5/6.
