Question

Keisha is reading a 325-page book at a rate of 25 pages per day. Use a point-slope equation to determine
whether she will finish reading the book in 10 days.

Answer 1

To determine whether Keisha will be able to finish reading the book in 10 days, establish first the point-slope form of the scenario.

If we let y be the number of pages in a book and x be the number of days the slope-intercept form is as follows:
    y = 25x

To determine the value of x if y is equal to 325,
   325 = (25)(x) 

    x = 325/25
    x = 13

Since the value of x is greater than 10 then, Keisha will not be able to finish reading the book.
