B
x + y = 7 4x + 9y = 20
2x + 6y = 5 3x – 9y = 1

Come up with a new linear function that has a slope that falls in the range 10 m − < < . choose two different initial values. for this new linear function, what happens to the function’s values after many iterations? are the function’s values getting close to a particular number in each case?
