Match the equation with the graph.
-1/2x+1/6y=2/3

Just sub x values into your equation and see which graph has those same points
OpenStudy (australopithecus):
follow?
OpenStudy (anonymous):
ahh.. kinda
OpenStudy (superdavesuper):
Or u can just put x=0 n y=0....sorry for sounding like a broken CD here ;)

Is it A or B?
OpenStudy (superdavesuper):
Big difference - when x=0, the y-intercept should be...
OpenStudy (anonymous):
2/3
OpenStudy (superdavesuper):
n when y=0...
OpenStudy (superdavesuper):
wait wait wait x=0, y is not 2/3....

The closes one looks like B.
OpenStudy (australopithecus):
If you had the equation,
2x = y
you can just sub values in it and graph it,
make a table,
|dw:1389402389720:dw|
Now match the points to your graph
OpenStudy (australopithecus):
so the graph would look like,
|dw:1389402470568:dw|
OpenStudy (superdavesuper):
u got the x-intercept part right (when y=0) but find the y-intercept at x=0 plz?
OpenStudy (anonymous):
1/6

None of them look like thay...
OpenStudy (australopithecus):
to give you an example, of what im doing to generate these points,
2x = y
so set x = 1
2(1) = y
y = 2
so set x = 2
2(2) = y
4 = y
Hope this helps
OpenStudy (superdavesuper):
when x=0, 1/6y=2/3...
OpenStudy (anonymous):
It is D??
OpenStudy (anonymous):
That is what I got.

oh yeah you need to solve for y
OpenStudy (australopithecus):
yeah D is right
OpenStudy (superdavesuper):
Sorry im back now n yes u got it @amandaaa00rouseee :)
