x-3y=9
What are you asked to do?
It says graph each equation using the slope and y-intercept
Ok, then first we nned to write it in the slope-intercept form. To do that, solve the equation for y.

that doesn't work julianchico and I don't know how to solve for y :(
Do I add 3y to each side or something
Since -3y is on the left side, I suggest you leave it there and instead, subtract x from both sides.
Hey again, you want y to be alone, so start by getting rid of the x that is on the same side as y
x-3y=9 -x -x ------------ -3y= 9x?
Close: x-3y=9 -x -x ------- -3y=9-x
You want to get y completely alone, so how can you get rid of the coefficient -3?
