can you solve this pls???

ok take a cartesian co - ordinate system, but not screen co - ordinates as Y goes up posittive.
The equation is Y = 3 and Solve X is the question. The author tells you to input a few numbers into the equation, here is it:
So Y = 3 is the same as the Ax + By = C form when you go - 0x + 1y = 3.
1) x = -1.
2) x = 0.
3) x = 1.
So obviously the idea is to plug those value sinto the equation but then she gives the answers and they look like this...(p.s. if you where plotting this on a graph, which i am, then y will always = 3.)
I can solve it for (4,3) but then the rest just dont add up at all.. :blink: I cant believe how I and many others have been made to feel thick by being stumped with this easy question... :blink: :blush:
Please guys hope you can help, which one will be the genious that does it ? :P

He who knows not and knows that he knows not is ignorant. Teach him.
He who knows not and knows not that he knows not is a fool. Shun him.

I think the confusion is coming from trying to plug the coordinates into the formula in the original post. I don't recall all the rules, but I don't think it is meant to be used in all cases??
Anyway, I hope this helps somewhat..
