The data in the table compares x, the number of pages in a chapter, to y, the amount of time, in minutes, spent reading. The function y = 0.86x - 0.09 models the data in the table. A 2-column table with 5 rows. The first column is labeled pages in a chapter with entries 10, 12, 5, 26, 20. The second column is labeled time spent reading (minutes) with entries 8, 11, 4, 22, 17. Which is the best prediction for the number of pages in a chapter that takes 18 minutes to read? 15 17 19 21

Answer:The answer is A, 15 I believe if i did the math right.

Step-by-step explanation: First you take the equation: f (x) = 0.86x-0.09

Then you plug in x witch in this case is 18 so f (18) = 0.86 (18) - 0.09 = 15.39 So round to the nearest whole number and you get 15.
