Answer:

Final answer is A. 9(3x+1)(3x-2).

Step-by-step explanation:

Given expression is 81x^2-27x-18.

81x^2-27x-18

=9(9x^2-3x-2)

We can factor that by splitting middle term into two parts then do grouping as shown below:

=9(9x^2-6x+3x-2)

=9(3x(3x-2)+1(3x-2))

=9(3x+1)(3x-2)

Which correctly matches with choice A. 9(3x+1)(3x-2).

Hence final answer is A. 9(3x+1)(3x-2).

Answer:

-2

Step-by-step explanation:

To find the slope of a line, you need to find the \frac{rise}{run} between two points. I will be using the points (-3, 2) and (-1, -2).

\frac{rise}{run} = \frac{-2-2}{-1-(-3)}

     = \frac{-2-2}{-1+3}

     = \frac{-4}{2}

     = -2
