Question:

What is the x-coordinate of a point on the y-axis? [Page No. 7]

Answer: Verified

The x-coordinate of any point on the y-axis is 0. A point on the y-axis is neither to the left nor to the right of it, so its horizontal distance is zero. Therefore, every point on the y-axis has the form (0, y).
