Learn how to plot coordinates and create straight line graphs to show the relationship between two variables. Also, plot graphs that contain a negative coefficient of x.

Coordinates are points on a graph. Find out how to plot data in this KS3 maths video.

You can make an Excel scatter plot assigning one of the variables in each record to the x-coordinate and one to the y-coordinate on a standard graph axis.

The film demonstrates how to plot ordered pairs on coordinate axes, forming a straight line that represents linear relationships in first-degree equations.

The goal was simple yet challenging, to help the ones in Class VIII understand how to plot coordinates on the Cartesian plane and identify different types of quadrilaterals.
