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 ...

If you are working at Higher tier, make sure you are confident with dividing fractions to work with gradients of perpendicular lines. To show that two lines are parallel, they must have the same ...
