Systems of Equations – One Solution

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).


How can we determine whether a line goes through the point (1, 1)?


One answer is y = (0/9)x + 1,  y = (-4/2)x + 3, and y= (-6/-1)x + -5.

  1. 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)
