Zero. A horizontal line has an equation of the form y=n, where n is a number, which can also be written as y=0x+n. Note that because x is multiplied by zero, the function does not vary with x, that is, the function does not change horizontally.
The slope of y = -1 is 0. This is because the equation is a horizontal line with a constant y-value of -1, meaning it does not change in the y-direction.
On the Cartesian plane the horizontal number line is the x axis.
The x-axis.

The horizontal line in the Cartesian plane is called the x-axis or x-coordinate.
