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 ...

Remember that to find the equation of a straight line you need to know its gradient and a point on the line. In some instances you are told the value of the gradient, however there are times where you ...
