$$x+3y=3$$ is the same as$$x=(-1/3)x+1$$

rhondasommer · Answer

y=mx +b 
and m = slope and b=y intercept. so your y intercept is 1. and your slope is -1/3

Well I just wanted to know if it was line A?

rhondasommer · Answer

how did you get line a though? did you guess?

rhondasommer · Answer

or did you do the math?

neycuurose1 · Answer

I did the math of course, I was wondering if it was line A

rhondasommer · Answer

yes it is. but if you did the math you would have no doubt. the y intercept being 1 you then go by slope; which is -1/3 so go down 1 and to the right 3. (which is line A)

neycuurose1 · Answer

I second guess myself. I doubted that it was the answer, and I wanted to be sure.

rhondasommer · Answer

dont doubt yourself :) yes that is the answer.
