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.

Revise how to plot a linear equation graph. Learn how to read x and y coordinates from a graph in this BBC Bitesize maths KS3 guide.

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.
