Answer:
slope = 2
Step-by-step explanation:
See the attachment for the markup.
It is usually convenient to choose places where the graph crosses grid intersections. Here, the graph crosses the x- and y-axes at integer values, so those points could be used, for example. We chose points away from the axes so that the rise and run lines could be seen more easily.
The graph has a rise/run of ...
slope = rise/run = 2/1 = 2
The slope of the line is 2.

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 :
