Answer:
3
Step-by-step explanation:
First you gotta take the equation and bring it to the following form:

The slope of the line is the coefficient of x, a.
In other words:

So, as we can see, the number infront of x is 3. That is to say that the slope of this line is equal to 3.
For A I am pretty sure it's 12.6 and for B I believe it's 15.7

Answer:
x²-(i-3)x- 3i
Step-by-step explanation:
What is a third-degree polynomial function P(x) with rational coefficients so that P(x) = 0 has roots −3 and i?
Given the toots of the polynomial to be -3 and i, the factors of the polynomial will be (x+3) and (x-i)
Taking the product
P(x) = (x+3)(x-i)
P(x) = x²-xi+3x-3i
P(x) = x²-(i-3)x- 3i
Hence the required polynomial is
x²-(i-3)x- 3i
