If y - 4 = 2x, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

{ (2, 1), (4, 2), (6, 3) }

{ (1, 2), (2, 4), (3, 6) }

{ (4, 0), (6, 1), (8, 2) }

{ (0, 4), (1, 6), (2, 8) }

The first thing we want to do is to make the equation a function, so we put y by itself on one side,

Add 4 to both sides

y = 2x + 4 <<< This is the equation that we will use

So if we input these numbers in,

The answer seems to be D. Where if x = 0 then y = 4 and so on
