Question

Please helllppppp!? :D


Which of the below systems of equations matches the following graph?


x – 3y = 9
2x + 3y = 0

x + 3y = –9
2x + 3y = 0

x – 3y = –9
2x – 3y = 0

x + 3y = 9
2x – 3y = 0

Answer 1

you sort of need the graphs?

Answer 2

I know.. i have one

Answer 3

Can you post a picture of the graph then I can try to help?

Answer 4

yes. one sec! :)

Answer 5

Just take some points on the graph and substitute them in the equation. Whatever equations satisfy the point are your equations

Answer 6

satisfy the point in the sense which give 0 on substitution of x and y co-ordinates in the place of x and y

Answer 7

I don't know how to get the graph on here :/

Answer 8

oh wait! its right there

Answer 9

they both intersect at (2,3)
so if we substitute these equations in the above equations none satisfy
so none of the equations match the graph

Answer 10

hmm.... thats not one of the answers?

Answer 11

no

Answer 12

Well, I'm confused then..

Answer 13

The point of intersection is (3,2) not (2,3)

Answer 14

yeah sorry I'm wrong

Answer 15

in that case the last set is your answer
try substituting 2 and 3 in the place of x and y

Answer 16

So, would this be the answer? x – 3y = –9
2x – 3y = 0

Answer 17

no x+3y=9 (3+3*2=9)
and 2x-3y=o (2*3-3*2=0)

Answer 18

ahh. i was going to chose that one
