I get confused about how to do the equation 3x+y=3, would it be y=-3x+3? and what number can I use in order to plug in, can i use 0, 4, and -4. Thank you very much

This is a equation of a line. if you put the equation into slope intercept form ( y = mx + b) you can easily get a long list of coordinates.
y = -3x + 3
Which means one point (y-intercept) is (0,3) as given by the constant. The slope, as given by the coefficient of x, is the change in y of the change in x so for every increase in the value of x you decrease the value of y by three. If you want to calculate a certain value pair just plug in the value and calculate or you can graph the line, either way the point for all integer values of x from -4 to 4 are listed below.
(-4,15)
(-3,12)
(-2,9)
(-1,6)
(0,3)
(1,0)
(2,-3)
(3,-6)
(4,-9)

You can move any term from one side of the equation to the other as long as you change its sign. So y = -3x +3 is totally correct.
You can plug in any value you like for x and then determine the corresponding value for y. It's usually best to pick 0 or 1.

3x+y=3.
First you need to get Y by itself by subtrcting 3x with -3x and place the number and variable on the right side of Y=3 which will give you y=3-3x

we can't solve x and y in this equation because there are too many values for x and y. This equation can only be solved when you have the 2nd function go together with 3x+y=-3.

to get y=-3x+3 you just isolate the y of the original equation then put all the numbers to the other side.. you can plug in any number you want.

y=3-3x.
u can use any values to get co ordinates in the grap to plot a straight line.

I haven't done a problem like this in years but it looks to me like x could be 1 and y could be 0. But that's too easy.. it has to be more complicated than that! haha

Well, you can put the numbers you want it it.
You want to use 0,4,-4 for what? x values?
