Topic

Geometry

Description

This example focuses on plotting coordinates along the x-axis of the Cartesian Coordinate Plane. The image shows four points: (-1, 0), (-5, 0), (0, 0), and (9, 0). These points are all located on the x-axis, where the y-coordinate is always zero.

Understanding how to plot points on the axes is a fundamental skill in coordinate geometry. This example helps students visualize the concept that all points on the x-axis have a y-coordinate of zero, regardless of their x-coordinate value.

By providing multiple examples of points on the x-axis, including the origin (0, 0), students can develop a clear understanding of this important concept in the Cartesian coordinate system.

Teacher's Script: Take a close look at these points. Notice how they all lie on the x-axis. What do you observe about their y-coordinates? Can you explain why all points on the x-axis have a y-coordinate of zero? Let's discuss how this relates to the definition of the x-axis and its role in the coordinate plane.
