Question

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

ordered pairs?
O{(0, -2), (1, 6), (2, 14)
O {(0, -2), (2, 13), (-5, -40)}
O {(1,7), (2, 7), (3, 7)}
O {(1,6), (2, 13), (3, 24)}​

Answer 1

{(0, -2), (1, 6), (2, 14)}

Explanation:

Answer 2

{(0, -2), (1, 6), (2, 14)}

Explanation:

The given equation is

`y=8x-2`

Notice that this equation represents a linear graph, because it's a linear equation.

Now, to know which pair belongs to this equation, we just need to evaluate them.

For
`x=0`

`y=8(0)-2=-2`

For
`x=1`

`y=8(1)-2=6`

For
`x=2`

`y=8(2)-2=16-2=14`

Therefore, the first set belongs to the fiven equation, so the answer is the first choice.
