Answer:
A solid horizontal line across -4. I've attached a picture of the graph down below
Step-by-step explanation:
Since there is no independent variable (x) in the equation, the dependent variable does not change and stays the same.
In other words, no matter what x is, y will always be -4.
In picture form, that would be a solid horizontal line across -4, since slope is 0 and y is unchanging.
