The graphs above, \(y = 2x + 1\) and \(y = 2x - 2\) have the same gradient of 2. The lines are parallel. State the equation of a line that is parallel to \(y = 3x + 7\). To be parallel, two lines must ...

Graphs are often used in everyday life to give information about how two quantities are related. The gradient and intercept of the graph can be interpreted from the graphs. Before reading this guide, ...
