Which of the following functions are linear?

Question

Two function tables, each giving x and y coordinate pairs. Function A gives the following pairs. (1, 7), (4, 8.5), (7, 10), (10, 11.5), and (13, 13). Function B gives the following pairs. (3, 2), (13, 4), (23, 8), (33, 16), and (43, 32).

Function A


Function B


Function A and Function B


None of the above

Answer 1

Function A is linear because the y values increase by a constant rate as x increases. Function B is not linear because the y values do not increase at a constant rate as x increases. Therefore, only Function A is linear.
