Izzy and Amie made the zero with a line through it!
How about "is always zero"?
A straight line passes through the x-axis one time, if its slope is non-zero, or not at all, if its slope is zero.
The slope is zero.
A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.
The graph of [ y = 7 ] is a straight horizontal line, passing through the point [ y = 7 ]on the y-axis. The slope of a horizontal line is zero.

How about "is always zero"?
The slope of a line is the tangent of the angle made by the line with the X-axis. Since for a horizontal line, this angle is 0 and tan(0) = zero, the slope of a horizontal line is zero.

sometimes zero
A straight line passes through the x-axis one time, if its slope is non-zero, or not at all, if its slope is zero.
The line going through an "o" helps to clarify the letter o, from the number zero.
The equator is the line made up of every point on Earth at zero latitude.
Greenwich, England
The symbol is a zero with a diagonal line through it.

The y-axis on a graph is the line that runs up and down through zero. The x-axis is the line that runs horizontally through zero. Both lines help people make their measurements in math.
