The equation of a straight line on a graph is made up of a \(y\) term, an \(x\) term and a number, and can be written in the form of \(y = mx + c\). For a line with equation \({y}={2}{x}+{ ...

This is known as the gradient. \(c\) is the number where the line crosses the \(y\)-axis. This is the \(y\)-intercept. To draw a graph of \(y = mx + c\) for given values of \(x\): Use the pairs of ...
