Courtney reads 38 pages of a book each day. In 9 days she will be be finished with the 489 pages of the book. Assume the relationship is linear. Find and interpret the rate of change and initial value. Then write the equation of the function in the form y=mx+b, where b represents the number of days and y represents the total number of pages read.
y=38x+147
