A point has a y-coordinate equal to 0. Where does it lie?

1. The rule for points on the axes states that a y-coordinate of 0 places the point on the x-axis, with coordinates in the form (a, 0). 2. An x-coordinate of 0, not a y-coordinate of 0, is what places a point on the y-axis instead. 3. Only the single point (0, 0) is the origin, and every point with y equal to 0 still lies somewhere on the coordinate plane, on the x-axis. _Source: OpenStax Elementary Algebra (CC BY 4.0), Ch 4 "Graphs", section 4.1 Use the Rectangular Coordinate System_
