Answer
This is what the graph would look like:
Work Step by Step
First off, from the equation we can tell that the graph will be a linear graph. It will be a straight line because it only goes up to the power of one.
Also, we notice there are no variables in the equation.
So the graph simply equals just $y$ $=$ $-2$!
So go down the y-axis until you reach $-2$, and draw a horizontal line along it.
