You can make a line graph in Excel in a matter of seconds using data already entered into the spreadsheet.

Lines which are parallel have the same gradient. For example, \(\text{y = 2x + 1}\) and \(\text{y = 2x - 2}\) will be parallel because they both have a gradient of 2. We want to determine if the lines ...

This educational film teaches viewers how to construct mathematical line graphs to solve algebraic problems. It begins by reviewing statistical graphs and then explains the relationship between ...

In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient of a line is calculated by dividing the difference in the ...
