In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed ... has a vertical movement of 2 down, the line has a gradient ...

The graph of \(y = 2x - 2\) crosses the \(y\)-axis at (0 ... Gradients can be: positive – going up negative – going down zero - no change (a flat line) Steep lines will have high gradients ...
