-12 (?)
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
4x-2y = 12 -2y = -4x+12 y = 2x-6 Therefore the y intercept is -6 and the slope is 2
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
4x+2y = 12 2y = -4x+12 y = -2x+6 So the y intercept is 6 and the slope is -2
4x + 6 = 6x - 12-4x -4x6 = 2x - 12+12 +1218 = 2xx=9
-12 (?)
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
4x-2y = 12 -2y = -4x+12 y = 2x-6 Therefore the y intercept is -6 and the slope is 2
-6
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
4x+2y = 12 2y = -4x+12 y = -2x+6 So the y intercept is 6 and the slope is -2
X = -12 I hope.
If: 2y-4x = -12 Then: y = 2x-6 So the y intercept is -6 and the slope is 2
2y-4x=-12 Add 4x to each side 2y=4x-12 Divide each side by 2 y=2x-6 The y-intercept is (0,-6)
x = -2 and x = 6
2x-3=4x+9 -2x-12=0 2x=-12 x=-6
