Question

Maddie has read 30 pages of a book. Her plan is to read 40 pages each day from this point on. Write an equation in slope-intercept form to represent the situation.

Answer 1

P = 30 + 40d

Explanation:

30 pages that Maddie has read of a book. Her plan is to read 40 pages each day from this point on.

If we represent the time as d days and the total number of pages that Maddie has read is given by P, then the equation that can model the situation is

P = 30 + 40d........ (1) in slope-intercept form.

Here, 30 pages are the initial value of the function i.e. at d = 0, P = 30 and 40 represents the number of page reading per day. (Answer)
