The slope is -2
y = 6x+8 is already in slope intercept form
First you need to solve for y like this: 6x+3y=8 3y=-6x+8 y=-2x+8/3 Once you have the equation solved for y, the coefficient of x equals the slope: slope = -2
6x+3y = 8 3y = -6x+8 y = -3x+8/3 The slope of the line is -3
y = -2x - 8
The slope is 3. --------------------- 2y = 6x +8 /2 /2 /2 y = 3x + 4 Now that it's in y = mx + b form, m = slope, m= 3
2y = 6x - 8y = 3x - 4========m(slope) = 3=========
-2 or written as a slope - 2/1
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
6x + 8 = 13, 6x = 13 - 8, 6x = 5, x = 5/6
y=6x-16 y=-2x+8
6x+4=52 6x=48 x=8
