You can put this solution on YOUR website!
You want to convert each equation into y=mx%2Bb form.
For your first equation, I don't know where you equal sign is.
I'll assume it is x=y-3
-y=-x-3
y=x%2B3
graph%28300%2C200%2C-5%2C5%2C-5%2C5%2Cx%2B3%29
Second equation
x=3y
-3y=-x
y=%281%2F3%29x
graph%28300%2C200%2C-5%2C5%2C-5%2C5%2C%281%2F3%29x%29
Hope this helps!
