Question

The table shows ordered pairs of the function y = 16 + 0.5x .

A 2-column table with 6 rows. The first column is labeled x with entries negative 4, negative 2, 0, 1, x, 10. The second column is labeled y with entries 14, 15, 16, 16.5, y, 21.
Which ordered pair could be the missing values represented by (x, y)?

Answer 1

Any pair satisfying y = 16 + 0.5x will work. For example, choosing x = 2 gives y = 16 + 0.5(2) = 17. So (2, 17) could be the missing ordered pair.
