Answer:
2 seconds
Step-by-step explanation:
the slope is -6/5. This is because it goes down 6, and then to the right for 5. You can also use the slope formula to solve this.
M = -12
point = (0, 1/2)
Find the slope-intercept equation
y - y₁ = m(x - x₁)
y - 1/2 = -12 (x - 0)
y - 1/2 = -12x
y = -12x + 1/2


The answer is either B, and you forgot to put in the ^2 in the answer choice, or C, and you forgot to put an x where there is a _ in the question.
Check the actual question (the one you recieved, not the one posted here) and see where the mistakes are. If f(x) = 8x - 4x - x^3, then your answer is C. However, if B is actually -x^3 + x^2 + 3x - 1, then the answer is B.
The line that is most likely to have a slope of 10 is the second one down
