The rate of reading in pages per hour, is the slope, rate of change, of the line in the graph, and in the table`

danjs · Answer

For Don...Using any 2 points on the graph, calculating the slope...
Done rate of reading = 
(108-72)/(6-4) = ???   pages per hour

danjs · Answer

For jacob, use any two points in the table...
Jacob's rate of reading =
(147 - 105) /(7 - 5) = ???  pages per hour
