Question 14 • Applications and Modeling
From (7, 16) to (9, 17), x increases by 2 while y increases by 1, so the rate of change is 1/2. To go from y = 17 to y = 18, x must increase by 2, giving the missing x-value 11. From x = 11 to x = 13, y increases by 1, so the missing y-value is 19. The correct choice is D: missing x = 11 and missing y = 19.
