Sanjay said that if a line has a slope of zero, then it never touches the x-axis. Which line proves that his statement is incorrect?

A line with slope zero is horizontal, so it has an equation of the form y = constant. The line y = 0 is horizontal and lies directly on the x-axis, so it touches the x-axis. Therefore, “y = 0” proves Sanjay’s statement incorrect.
