Factor x^3 -2x^2-9x+18
= x^2(x - 2) - 9(x - 2)
= (x^2 - 9)(x -2)
= (x + 3 )(x - 3)(x - 2)
So (x+3) is a factor
Dividing:-
x + 3) x^3 - 2x^2 - 9x + 18 { x^2 - 5x + 6
x^3 + 3x^2
----------------
-5x^2 - 9x
-5x^2 - 15x
6x + 18
.............
The quotient is x^2 - 5x + 6
which is (x - 3)(x - 2)
So the factors of the original expression
= (x + 3)(x - 3)(x - 2) answer

Answer from Gauth math
The equation for the slope-intercept is y =3x-4
It is either A or B. I am not certain only because I do not know if your assignement is indicating that the underlined greater sign represents an open dot or a closed dot
-20/7
5m +72 = -2m + 52
5m + 2m = 52-72
7m = -20
m = -20/7
