Bill is a taxi driver.
You can use this graph to find the cost of a taxi for different distances.
The graph shows a linear relationship between distance and cost. The y-intercept is at £5, which represents the fixed charge. The line passes through the points (0, 5), (10, 20), and (20, 35). The grid has major lines every 5 units on both axes and minor lines every 1 unit.
| Distance (miles) | Journey Cost (£) |
|---|---|
| 0 | 5 |
| 5 | 12.5 |
| 10 | 20 |
| 15 | 27.5 |
| 20 | 35 |
| 25 | 42.5 |
A line graph showing Journey Cost (£) on the y-axis (0 to 50) versus Distance (miles) on the x-axis (0 to 25). The line starts at (0, 5) and passes through (10, 20) and (20, 35).
For each journey there is a fixed charge plus a charge for the distance.
How much is the fixed charge?
Bill makes two journeys.
The distance of one journey is 10 miles further than the other journey.
Work out the difference between the two journey costs.
