SOLUTION: Solve each of the following systems by graphing: x - 2y = 8 3x - 2y = 12 and 3x - 6y = 9 x

SOLUTION: Solve each of the following systems by graphing: x - 2y = 8 3x - 2y = 12 and 3x - 6y = 9 x - 2y = 3

Question 107522: Solve each of the following systems by graphing:
x - 2y = 8
3x - 2y = 12
and
3x - 6y = 9
x - 2y = 3

x-2y=8 or -2y=-x+8 or y=-x/-2+8/-2 or y=x/2-4 (red line)
3x-2y=12 or -2y=-3x+12 or y=-3x/-2+12/-2 or y=3x/2-6 (green line)
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = x/2 -4 and y = 3x/2 -6).
------------------------------------------------------------------------
3x-6y=9 or -6y=-3x+9 or y=-3x/-6+9/-6 or y=x/2-3/2 (red line)
x-2y=3 or -2y=-x+3 or y=-x/-2+3/-2 or y=x/2-3/2 (green line)
these 2 equations are identical therefore there is no unique solution or no intersect.
