Predicting Values: Once you have a linear equation that represents a relationship, you can use it to predict values. For example, if you know the cost of producing a certain number of items, you can ...

Plot points with coordinates where \(x\) and \(y\) are equal. Three points are sufficient, but more can be plotted. Draw a line through the plotted points. If \(x\) is positive, \(y\) is negative. If ...

Matching linear equations with their corresponding graphs is a fundamental skill in algebra and a crucial stepping stone for understanding more complex mathematical concepts. This exercise not only ...

Any straight line graph has a constant gradient, which is calculated by the change in 𝑦 divided by the change in 𝑥, along any section of the graph. The gradient is measuring the steepness of the ...

Wrestling with Word’s equation editor can be frustrating, but it doesn’t have to be. A few simple tricks can make typing and formatting math equations a breeze—no more clunky menus or endless ...

LaTeX or Word? For physicists and mathematicians, the choice is obvious. But for scientists in other fields the merits of LaTeX have largely gone unnoticed. The open-source software system — used to ...
