Understand Basic Ax+Bx=C
Posted:

Hello, I'm reading a book trying to catch up on my geometry. In the book I can't for the life of me figure out how the author devised some of the answers he's been giving.
In the simple equation y=3 he converts it to Ax+Bx=C equaling 0x+1y=3. Earlier he stated that "The graph of an equation of the form Ax+By=C, where A and B are not both 0, is a straight line." A is 0 and the equation results in a straight line.
In the second part of the problem he states: "Pick three x values, such as 0, 1, 1. When you plug them into the equation, you get the three ordered pairs (0,3), (4,3), and (4,3)."
How is it if you put 0, 1, and 1 as x you get anything that isn't 0, 1, and 1 as x. I have no idea how the answers 0, 4, and 4 were came up with.
I'm totally confused I left the question and starting other problems. Appreciate any help that is offered. Thanks
