Gradients can be: positive – going up negative – going down zero - no change (a flat line ... x + 1\) or \(y = − \frac{3}{4} x + 2\). Horizontal lines have a gradient of 0 and equations ...

In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient of a line is calculated by dividing the difference in ...
