If y = 8x - 2, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

{ (-1,-1), (3, 15), (4,0) }

O{ (7,35), (4, 17), (2, 10) }

{ (2,5), (8,50), (9,66) }

O{ (-2, - 18), (2, 14), (0, - 2) }

Answer: The right option that represents possible inputs and outputs of the function is the ordered pair

{ (-2, - 18), (2, 14), (0, - 2) }

Step-by-step explanation:

By crosschecking;

Y=8x-2

When x=-2, y = 8 (-2) - 2, y = - 16-2, y=-18. (-2,-18)

When x=2, y = 8 (2) - 2, y = 16-2, y = 14

(2,14)

When x=0, y = 8 (0) - 2, y = 0-2, y = - 2

(0,-2)
