Question 279324
x+3y=3
y=-1/3x+3 

sketch graph i need to know the coordinates of each problem and the point where they intersect
------------------------
I have no idea what "the coordinates of each problem" means.
x+3y=3
y=-1/3x+3 --> x+3y = 9
These are 2 parallel lines, no intersection, no solution.
-----------------------------
To graph them, you need 2 points for each.
Pick values for x and find y.
Plot the points, draw a line thru the pair.
