Question

If y = 6x - 4 which of the following sets represents possible inputs and outputs of the function represented as ordered pairs?

Answer 1

The only of these that is a proper set of ordered pairs for this equations is A) (0,-4) (1,2) (3,14)

In order to prove this, you need to put each ordered pair into the equation and prove that it is a true statement. Below are the examples of this for A.

(0, -4)

y = 6x - 4

-4 = 6(0) - 4

-4 = 0 - 4

-4 = -4 (TRUE)

(1, 2)

y = 6x - 4

2 = 6(1) - 4

2 = 6 - 4

2 = 2 (TRUE)

(3, 14)

y = 6x - 4

14 = 6(3) - 4

14 = 18 - 4

14 = 14 (TRUE)

Therefore, each of these ordered pairs works in the equation.
