So if you were to do every possible x you would end up getting a line that looks something like that... right over there. and any... any relation, if you pick any x and find any y it really represents a point on this line, or another way to think about it any point on this line represents a solution to this equation right over here. so if you have this point right over here. which looks like about x is 1 and a half. y is 2.
