These two equations are linearly dependent. In otherwords, they reduce to the same equation. Try putting y on the left hand side of the equation like this:
x + y = 1
y = 1 - x (after subtracting x from both sides)
Now do the same with the other equation:
4x + 4y = 4
4y = 4 - 4x (subtract 4x)
y = 1 - x (division by 4)
This essentially means that the two equations are the same.
Good luck.

For 4x+4y=4:
Subtract 4x from both sides. Now you have:
4y=-4x+4
Now divide both sides by 4. Now you have:
y=-x+1. Graph this using graphing paper.
Now, for x+y=1, simply subtract x from both sides leaving you with:
y=-x+1. Graph this on the same graphing paper.
They are exactly the same and intersect at wherever the are. I believe this is called independent meaning it has infinite possibilities of intersection.

4x+4y=4
4y=-4x+4
y=-x+1
x+y=1
y=-x+1
which means that both lines ore the same.
the b,or y-intercept is +1, and m, the slope is
-1/1, or 1 down,and 1 to the right.

those are equal, now all you have to do is graph them, unit 4 on the x-axis, unit 4 on the y-axis, should be equal to 4/1 squares apart from one another.
Forgive me if it's wrong, i haven't had Algebra in two years.

to solve this problem you first need to solve for y. To do this, subtract x from both sides of both equations and divide by y. Then take out the y and set the equations equal to each other. After you do this, solve for x. once you have reached a value for x, you plug it back into one of the equations and solve for y.

how am i supposed to tell u that?? i cant draw u a graph! if u look carefully, its actually a very easy graphing problem.

put it into the format y=mx+b. then graph from there. m is slope b is y intercept.

sorry but im done with those days, though you can get a TI 83+ calculator and it will do it for you!
