Graph the equation $2x=-11$ on a coordinate plane

The equation $2x=-11$ can be written as $x+0y=-\frac{11}{2}.$ Any ordered pair in the form $\left(-\frac{11}{2},k\right),$ where k is any real number, satisfies the equation. Thus, the graph of the given equation is a vertical line with $-\frac{11}{2}$ or $-5.5$ as its x-intercept. See the figure below.
