Question

If y = 7x – 5, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

Answer 1

{(–5, 0), (9, 2), (–26, –3)}
{(2, 7), (1, 6), (3, 13)}
{(0, –5), (2, 9), (–3, –26)}
{(1, 3), (6, 18), (8, 15)}

Answer 2

Plug in x for the 'x' in the equation and y for the 'y' in the equation. Solve, if they are equal, it is true.

Answer 3

You don't have to do all of them, just try the first one of each.

Answer 4

i dont understand on how to do it

Answer 5

Let's try the first one:

y = 7x – 5
{(–5, 0), (9, 2), (–26, –3)}

Let's take (-5, 0) and plug in.
x = -5
y = 0

0 = 7(-5) – 5
0 = -35 - 5
0 = -40

Since they are not equal, it is false, making A wrong.
