Answer:
The slope is
Step-by-step explanation:
Take the general equation of a straight line
Here is the slope of the line.
So let's get the equation of the line in the question in the same form.
Add to both sides:
Add to both sides:
Divide by to get it into the general equation:
Now compare it to the general equation to find the value of . The value of
is the coefficient of
which we can see is
Notice that we can simplify both numerator and denominator of our rational function. In the numerator we have a quadratic expression of the form 
. To to simplify it, we are going to find tow numbers that add to 2 and multiply to -8; those numbers are 4 and -2.
In the denominator we have a difference of squares:
Now we can rewrite our function:
From the simplified form of our rational function we can infer that its graph has two vertical asymptotes at
and 
We can conclude that the graphic of our rational function is:
