As you move along a line from left to right, you might go up, you might go down or you might not change at all. Gradient \(= \frac{\text{change up}}{\text{change right}}\) or \(\frac{\text{change ...

If we are given equation of the line instead of the graph, we can still determine the gradient. Equations of straight-line graphs are given in the form: \(\text{y = 2x - 1}\) The gradient is 2 and ...
