Answer

Explanation:

Step1: Calculate pages read in 1.5 hours

$480 - 402=78$

Step2: Calculate reading rate per hour

$\frac{78}{1.5}=52$ pages per hour

Step3: Form the linear - equation

The initial number of pages left is 480 and the number of pages left decreases at a rate of 52 pages per hour. So the equation is $y = 480-52x$.

Answer:

$y = 480 - 52x$
