Directions: Using the integers from -9 to 9, at most one time each, create a system of three-equations such that the solution is (1,1).
Hint
How can we determine whether a line goes through the point (1, 1)?
Answer
One answer is y = (0/9)x + 1, y = (-4/2)x + 3, and y= (-6/-1)x + -5.

That’s too easy!
I think i’m correct, but probably wrong if I didn’t follow the rules.
I think that the solution is;
1. y=x
2. y=-x+2
3. y=(0/n*)x +1
n* means every integer from -9 to 9, as it has been said on the rules (that is 0, obviously)
