    Answer:c. 1 page

    Step-by-step explanation:

    Let x represent the number of hours that Jones takes to finish the pages

    Let y represent the number of pages that Jones finishes in x hours.

    Jones has already taken 1 page of notes on his own. Therefore, the equation becomes

    y = 2x + 1

    After 4 hours,

    y = 2*4 + 1 = 8 + 1 = 9 pages.

    This equation is in the slope intercept form where

    m = Slope = 2 pages per hour of class

    To get the y intercept, we will substitute x = 0 into the equation. It becomes

    y = 2*0 + 1

    y = 1

    So the y intercept is 1 page
