For this case we have an equation of a line of the form:

Where:
m: It's the slope
b: It is the cutoff point with the y axis
We have the equation:

So, we have:

Answer:
The slope is
Answer: The only difference between the six functions depends on the sides we use.
Step-by-step explanation:
The primary trigonometry ratio are
Sine (sin)
Cosine (cos)
Tangent (tan)
The reciprocal ratio are derived from the three primary functions. Because they can easily be derived, calculators and spreadsheets do not usually have them. These are:
Secant (sec)
Cosecant (csc)
Cotangent (cot)

The answer is x2 + 2xy + y2.
