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 ...

Ms Alexandra Zbanca, 41, was found to be ‘under the influence of alcohol whilst at work’ and was convicted of a drink-driving ...

Any line with a gradient of 3 will be parallel to \(y = 3x + 7\). Two examples are \(y = 3x - 2\) and \(y = 3x + 11.6\). Find the equation of a straight line that is perpendicular to \(y = 2x + 1\).
