## 1.2 Segment and Step Graphs

### Segment Graphs

- Segment graphs consist of a series of straight-line graphs, creating
**one continuous line**. - Segment graphs are used to model situations which
**change at distinct points**. - Each segment can be analysed individually as a straight-line graph.

Example

Above is a segment graph modelling the distance a driver is from their house on a particular trip. We can see the first segment begins at (0,0) and ends at (1,40). We can use these points to find the gradient of the segment, which in this case, tells us the speed (km/hr) which the driver was travelling:
