3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
3x-y = 9 2x+y = 6 Add both equations together: 5x = 15 x = 3 and y = 0
-3x - 9 = 3y -x - 3 = y y = -(x+3)
9
y=-2/3x
3x-y=9 y=3x-9
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
-9
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
3x-y = 9 2x+y = 6 Add both equations together: 5x = 15 x = 3 and y = 0
3x+y=-1 y=-1-3x5x-y=9 5x-(-1-3x)=95x+1+3x=98x=8x=1y=-1-3(1)y=-4(1,-4)
your equation is y=3x + 4 here are five parallel equations... y=3x + 5 y=3x + 6 y=3x + 7 y=3x + 8 y=3x + 9
-3x - 9 = 3y -x - 3 = y y = -(x+3)
slope: -3 y-intercept: 9
3x+2y=9 2y=9-3x y=-1.5x-4.5
