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)}

D- (0.4)  (1,6) (2,8)

Step-by-step explanation:

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

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
