ANSWER :
The answer is :
EXPLANATION :
Note that cotangent is only positive when the angle is in the first or third quadrant.
Since y is not in the first quadrant, it must be in the third quadrant.
So the x and y are both negative.
An angle with a terminal point (x, y)
The cotangent is x/y
We can equate :
Since x and y are both negatives, x = -9 and y = -13
We can have the triangle :
The hypotenuse will be :
We are asked to find the value of sec y.
In an angle with a terminal point (x, y)
The secant is :
The hypotenuse is 5√10 and x = -9
The value of sec will be :

Option B. (-3) is a negative integer
Step-by-step explanation:
We will solve each expression one by one to check which option is a negative integer
A. 5 -(-6)
The double minus will be converted to + so
So it is a positive integer
C. -12 = (-6)
The minus signs on both sides of equation will be cancelled so it will also be a positive integer
B. (-3)
This is a negative integer as there is no operation being performed or no other sign.
So this is a negative integer
Hence,
Option B. (-3) is a negative integer
