y = 0. You can get this from the slope-intercept equation of the line.
A straight line through the origin, with a finite non-zero slope.
Abbreviation for Diameter(as used in Technical drawings).
Izzy and Amie made the zero with a line through it!
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.
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
The letter 'O' with a slash through it is the number 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 symbol is a zero with a diagonal line through it.
Greenwich, England
The equator is the line made up of every point on Earth at zero latitude.
