Y=3x-4
Because your slope is 3 when you do change in y over change in x. Y intercept is neg 4.
Answer:A that is what I think the answer is
Write the coeeficientes of the polynomial in order:
| 1 - 5 6 - 30
|
|
|
------------------------
After some trials you probe with 5
| 1 - 5 6 - 30
|
|
5 | 5 0 30
-----------------------------
1 0 6 0 <---- residue
Given that the residue is 0, 5 is a root.
The quotient is x^2 + 6 = 0, which does not have a real root.
Therefore, 5 is the only root. You can prove it by solving the polynomial x^2 + 6 = 0.
The rate of change is meaning the slope. The slope of A is 8, therefore, the answer would be 7.
hope this helps :)
