Question

If y – 4 = 2x, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs? (1 point)


{(2, 1), (4, 2), (6, 3)}
{(1, 2), (2, 4), (3, 6)}
{(4, 0), (6, 1), (8, 2)}
{(0, 4), (1, 6), (2, 8)}

Answer 1

@ccswims

Answer 2

Subsitute these values in for x and y :)

Answer 3

Try the first one in your equation :)

Answer 4

hmmm.... Im kinda slow lol

Answer 5

try solving for why, then solve for x

Answer 6

Lol. Okay, so the first value in the ordered pair is x right? So subsitute that for x :) same with y :)

Answer 7

this is the operational way to do it when you don't have any multiple choice

Answer 8

Plug in all the x coordinates and then compare them with all y coordinate outputs

Answer 9

"y" sorry not "why"

Answer 10

I was gonna say, @ccswims cx

Answer 11

Also if you change the function in to y=2x+4 then you know that all the y-values must be greater than the x-values

Answer 12

OH so the answer would be B!

Answer 13

E is also an option

Answer 14

lol

Answer 15

D sorry

Answer 16
