Make sure you are familiar with finding the equation of a line and calculating gradient to understand equations of parallel lines. If you are working at Higher tier, make sure you are confident ...

The lines are parallel. State the equation of a line that is parallel to \(y = 3x + 7\). To be parallel, two lines must have the same gradient. The gradient of \(y = 3x + 7\) is 3. Any line with a ...
