graph the equations shown beloe

Hello!
-----------------------------------------------------------------------------------------------------------------
I can't attach a photo here, so I will try to explain.
y=-2
The equation of any line looks like so:
y=mx+b
Here, we have only:
y=b
That doesn't mean that the slope vanished; the line still has a slope, but it equals 0.
So we have y=0x+b.
Now, b is the y-intercept (where the graph touches the y-axis).
So the graph touches the graph at (0, -2)
Now, what does 0 slope mean?
It means that the line is horizontal.
Hope it helps you!
