Answer
$$\text{slope}=-\dfrac{11}{2}$$
Work Step by Step
RECALL:
The standard form of a line's equation is $Ax+by=C$.
The slope $m$ of the line is given by the formula $m=-\dfrac{A}{B}, B\ne0$.
The given equation is in standard form with $A=11$ and $b=2$.
Thus, the slope of the line is:
$$m=-\dfrac{A}{B}=-\dfrac{11}{2}$$
