The function ƒ (x) = - 3x + 5 is represented by which set of ordered pairs?

1.{ (-1, 8), (0, 5), (2, - 1), (3, - 4) }

2.{ (-1, 9), (0, 2), (1, 7), (2, 13) }

3.{ (-2, 8), (-1, 16), (0, 14), (1, 2) }

Answer:1

Step-by-step explanation:

Just substitute the ordered pair and see which make the function work.

The correct answer is the first set { (-1, 8), (0, 5), (2, - 1), (3, - 4) }

Step-by-step explanation:

In order to determine if the set works, input each ordered pair to see if the statement ends up true. The first two ordered pairs are done below.

(-1, 8)

f (x) = - 3x + 5

8 = - 3 (-1) + 5

8 = 3 + 5

8 = 8 (TRUE)

(0, 5)

f (x) = - 3x + 5

5 = - 3 (0) + 5

5 = 0 + 5

5 = 5 (TRUE)
