Darwin Lam · 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.

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) }

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) }
