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.

Graph forms All vertical line graphs have an equation of the form: x = c For example: x = 1, x = 3, x = 4, etc All horizontal line graphs have an equation of the form: y = c For example: y = 3, y ...

If you need to create a Line Chart and Scatter Plot in Excel, read through this article. We have also explained which one is right for you.

The line graph of the complete bipartite graph on sets with m and n vertices, denoted by L (Bmn), is the graph with mn vertices given by all ordered pairs (i, j), 1 ≤ i ≤ m, 1 ≤ j ≤ n.

We discuss a comment on a previous post stating that the text of labels on the vertical axis of graphs must be horizontal by discussing the pros and cons of four possible positions for these labels.
