Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 9, - 4) and (x₂, y₂ ) = (- 3, - 6)
m =
=
= - 
(4x-3)(x+5)
= 4x^2+20x-3x-15
= 4x^2+ 17x -15.
The final answer is 4x^2+ 17x -15~
The answer would be about 8/12 because you must convert 4/6 into 8/12. 8/12 + 3/12=11/12
1/4 would be about 3/12, so 11/12 - 3/12=8/12.
