Homework Help: math/algebra

Posted by ms jay on Thursday, August 23, 2007 at 9:23am.

I have a question of how do I determine the variables when graphing linear equation? For an example graph x+2y=4, how do you come up with the variables as (0,2) (2,1) and (4,0)? The example in my book does not tell me how they came up with this. I know how to graph, I need to know how to come up with the variables.
