Question 74722
3x-6y=9, -6y=-3x+9, y=-3x/-6+9/-6, y=x/2-3/2
x-2y=3, -2y=-x+3, y=-x/-2+3/-2, y=x/2-3/2
These two equations evolve into the same equation. Thus:
{{{ graph( 300, 200, -6, 5, -10, 10, y = x/2 -3/2, y = x/2 -3/2) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = x/2 -3/2 and y = x/2 -3/2).
