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 = a constant. The line y = 0 is the x-axis itself, so it touches the x-axis at every point on the line. Therefore, y = 0 proves Sanjay’s statement incorrect.
