Answer/Step-by-step explanation:
a. The order pair are:
(1, 6) => when x (distance) = 1, y (price) = 6
(3, 8) => when x (distance) = 3, y (price) = 8
(5, 10) => when x (distance) = 5, y (price) = 10
(7, 12) => when x (distance) = 7, y (price) = 12
{(1, 6) (3, 8), (5, 10), (7, 12)}
b. The graph represents a function because every domain value (x-value) has only one range value (y-value) that is related to each.
