you subtract x making it -y=-x+3 then divide everything by -1 making it y=x-3.After that you put it in a scientific calculator and i hope you can go of from here
Sorry my mistake did it wrong ok so wat u do is subtract the 3 making it -y=x-3 but u cant have a negative y so you divide everything by -1 so it should end up being y=-x+3
