SOLUTION: I am supposed to graph and identify the y-intercept, but no matter how hard I try I keep getting it wrong. The equation is x + 3y = 6. I know that you have to add -x to both sides

Question 242219: I am supposed to graph and identify the y-intercept, but no matter how hard I try I keep getting it wrong. The equation is x + 3y = 6. I know that you have to add -x to both sides so 3y = -x + 6. The example I have says to divide by 3 and then shows y=-1/3x + 2. How did they get 1/3 if they are dividing by 3. (I know it is probably a dumb question but I am an idiot when it comes to math)If I can just figure where the fraction came from then maybe I can get the rest of it. Can someone please help?

One thing to remember that when a variable like x is by itself, it is understood that the coefficient is 1. In this equation you would understand it as
3y = -1x + 6
Divide by 3
y = x +
which is
y = x + 2

the fraction is there because x is actually 1x, we just do not show it.
the equation really is 1x+3y=6.
so leave the one there
3y = -1x + 6
y = -1/3x + 2
I hope that helps you see why a fraction is there.
Oh and dumb people do not ask questions. So your a smart one in my book.
