Both the numerator and denominator are divisible by 6. You need to find the greatest common factor, or GCF, which in this case is 6. So divide both the top and the bottom by 6 and you get 2/-5, and that is your final answer in simplified form.
Answer:
Step-by-step explanation:
3x+6=12
-6. -6
3x=6
Divid three by both sides.
X=2

So we know the slope has to be -3 and the y intercept is 2. y intercept looks like (0,2). since we know this we automatically can rule out B since it has (0,0).
let’s find the slope of A
-9- -5
-3- - 1
the slope= -4/-2= 2
we know it’s not A because the slope is not -3
let’s find the slope of C
-17- -8
-5- -2
slope= -9/-3=3
we know it’s not C because the slope is not -3. we could directly assume that D is the answer no but we’ll still find the slope just to be sure
let’s find the slope of D
14-8
-4- -2
slope=6/-2= -3
the answer is D!!
2x + x - 1 x
= ------------------ * ---------
x(x - 1) 8
3x - 1
= --------------
8x - 8
