Understanding the Cartesian Plane

The video tutorial explains how to draw and name the x and y axes, number them with positive and negative values, and introduces the concept of coordinates. It describes how to identify a point on a plane using ordered pairs, emphasizing the importance of order in these pairs. The tutorial concludes with an introduction to the Cartesian coordinate system.

What do we call the horizontal axis in a Cartesian coordinate system?

• x-axis

• y-axis

• w-axis

• z-axis
