The cost of renting a bike at the local bike shop can be represented through the equation y = 2x + 2, where y is the total cost and x is the number of hours the bike is rented. Which of the subsequent ordered pairs would be a probably number of hours rented, x, and the corresponding total cost, y?
a. (0, -2)
b. (2, 6)
c. (6, 2)
d. (-2, -6)
Choices a and d should be omitted since the negative values should not form sense for this problem using time and cost. Choice b substituted would be 6 = 2(2) + 2 which simplexes to 6 = 4 + 2. Therefore, 6 = 6. The coordinates in choice c are reversed from choice b and will not work if substituted for x and y.
