Understanding Cartesian Coordinates

This video tutorial introduces Cartesian coordinates, explaining how they are used to specify locations in two dimensions. It covers the concepts of the origin and axes, and demonstrates how to plot points on a graph. The tutorial includes exercises to practice graphing points and identifying coordinates, and concludes with a brief mention of an adaptive program for further practice.

What is the primary purpose of Cartesian coordinates?

• To specify locations in four-dimensional space

• To specify locations in three-dimensional space

• To specify locations in two-dimensional space

• To specify locations in one-dimensional space
