Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.

If an equation can be rearranged into the form \(y = mx + c\), then its graph will be a straight line. In the above: \(x + y = 3\) can be rearranged as \(y = 3 – x\) (which can be re-written as \(y = ...

Microsoft Excel can present two series of data points together on the horizontal axis, but if the number scale for each series dramatically differs, the data will not be readable. Using a two-sided ...

The classic horizontal bar chart is something we’re all familiar with. For many of us, it was the first ‘chart’ we learnt in school, usually alongside Venn diagrams and line graphs. That’s because bar ...
