Question 71915
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 2 equations are the same therefore the 2 lines are the same.
{{{ 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).
