The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
The slope is -2
6x + 8 = 20 Subtract 8 from both sides: 6x = 12 Divide both sides by 6: x = 2
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2

The slope is -2
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
8x+2=6x+10 8x-6x=10-2 2x=8 x=4 Therefore, x=4.
It is translated upwards by 8 units.
6x + 8 = 20 Subtract 8 from both sides: 6x = 12 Divide both sides by 6: x = 2
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
6x + 8 = 6 6x = -2 x = -2/6 x = -1/3
6x + 8 = 13, 6x = 13 - 8, 6x = 5, x = 5/6
y=6x-16 y=-2x+8
6x+4=52 6x=48 x=8
