Question

need help with these pairs this site is so great ove been getting really nice help from nice people.

the ordered pairs (0,0) (2,4) (4,8) and (6,12) represent a funtion what is the rule of this function?

A. y=x+2
B. y=3x
C. y=x+4
D. y+2x

Answer 1

@josedavid

Answer 2

A or C

Answer 3

@Marie_Loves_You Do not give direct answers please

Its against CoC

Answer 4

im just looking for help can try and figure the rest out. not looking for an exact answer @WWWHHHAAATTT?

Answer 5

is a

Answer 6

What do you think it is?

Answer 7

im kind of leaning more towards A but im not positive can you help me work through it ? @WWWHHHAAATTT?

Answer 8

You need to just plug in the the coordinates for the equation. (x,y)

Answer 9

Ok, First. Give me an Explanation of why you think its A.

Answer 10

i have no idea @WWWHHHAAATTT?

Answer 11

Can you try at least?

Answer 12

If you use the first set of coordinates you would be able to cancel a couple of the answers because the pair is (0,0) which means x = 0 and y = 0 [ (x,y) (0,0) ] if you plug these values in for the equations you should see that two of the equations will not work.

Answer 13

ok so B and D wouldnt work because they dont fit with the coordinates? @Rhystic

Answer 14

First off is D y= 2x or y +2x = 0? secondly how are you plugging in the numbers? because it seems like you're just spouting stuff based off what marie said which is wrong by the way.

Answer 15

if you utilized (0,0) then B and D would be the only ones that work ...

Answer 16

sorry @Rhystic just trying to figure this out.

Answer 17

I'll do 0,0 for you.

Answer 18

A. y = x +2 -> 0 = 0 +2 2 is not = 0
B. y = 3x -> 0 = 3(0) this works.
C. y = x +4 -> 0 = 0 +4 0 is not = 4
D. y = 2x - > 0 = 2(0) this works.

You now have B & D left that might be correct. Take the next set of coordinates : (x,y) = (2,4) and plug them into B & D and see which one works.

Answer 19

Dayum @Rhystic you good

Almost to good

Answer 20

its D y+2x

Answer 21

And do what @rhystic did for all the point and just find an equation for which all these points work properly :)

Answer 22

correct ally good job.

Answer 23

thanks for all your help!!!1

Answer 24

SO GET OWNED @josedavid

Answer 25

You just got SHREKED
