Question

If y = 9x − 7, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
{(0, −7), (1, 2), (−1, −16)}
{(−7, 0), (2, 1), (−16, −1)}
{(1, 9), (2, 7), (3, 16)}
{(7, 9), (8, 10), (9, 11)}

Answer 1

For the first option: -7 = 9(0) - 7 = -7; 2 = 9(1) - 7 = 9 - 7 = 2; -16 = 9(-1) - 7 = -9 - 7 = -16
All ordered pairs in the first option satisfied the function. Hence the required answer.
