Plotting Points

How to plot points and name quadrants.

As we learn how to graph, we will need a thorough knowledge of the fundamentals of graphing: plotting points and identifying coordinates. One of the most important things to know is the terminology of what we call the Cartesian coordinate system, or an xy graph.

Graphing points in all four quadrants on the coordinate plane.

In this lesson you will learn to graph points in any quadrant by using a coordinate plane.

Standard 6.NS.8:

Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate.

To graph, or plot points we use two perpendicular number lines called axes. The point at which the axes cross is called the origin. Arrows on the axes indicate the positive directions.

Students learn how to plot points on a coordinate system.

How to plot a set of coordinates such as (-3, 5) on a graph.

This video shows how to plot and locate points on a grid using an (x,y) coordinate system, also known as ordered pairs. It also shows you how grids are divided into quadrants and how each quadrant has unique characteristics.
