Find slope of y + 4 = 9

Is this homework?

Yes

I'll give you a hint ; there's no x involved in the equation, just a y. So what would the graph look like? Consequently, what would its slope be?

The slope is the coefficient for the variable "X". There is no "X" in your equation, so the slope is zero.

Darn you! You posted just a couple of seconds before me!
