The pattern of a linear function, is the following:
y = mx + b
Where m is always the slope.
m in this case is -4, hence
The correct answer for your question is -4.
(2k² + 5k - 6)(3k - 1)
(6k³ - 2k² + 15k² - 5k - 18k + 6)
6k² + 13k² - 23k + 6
Use the FOIL method to simplify the problem.
(FOIL stands for first outer, inner, last)
