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 ...

To work out a gradient, use the scales of the axes and find how many units you go up or down for each unit you move right. To work out the equation of a line from a graph, find the gradient and ...
