Linear and nonlinear functions are the building blocks of algebra. They are essential to the understanding of graphs, equations, and the principles that govern the study of mathematics beyond the ...

The gradient of a linear function can be calculated from its rule, derived from a table of values, determined using two points, or found using rise over run on a graph. Below are four methods that can ...

A linear equation is drawn as a straight line on a set of axes. To draw the graph ... a table of values is used to create the coordinates. We use substitution to calculate the values. For example ...
