Answer:
A. ¾
B. 7½ pages
Explanation:
A. Constant of proportionality, k, =

In this case, y = pages, while x = days.
Take any coordinate pair to calculate the constant of proportionality, k. Let's use (3, 4).

Constant of proportionality = ¾.
B. Number of pages (y), Indira would read in 10 days (x).
Substitute x = 10 and k = ¾, into


Multiply both sides by 10




Number of pages Indira can read in 10 days is 7½ pages.
