Te gradient of a straight line is found by calculating \displaystyle \frac{rise}{step}

## Summary/Background

Straight lines have equations of the form y=mx+c, where c is the "y-intercept", in other words the point where the line crosses the y-axis. m is the gradient of the line, which can be found from the graph by constructing a triangle as shown to the right and measuring the "rise" and the "step". The gradient is given by "rise" divided by "step"
