This introduction covers Graphs That Tell Real Stories within Real-Life Graphs for GCSE Mathematics. Revise Real-Life Graphs in Graphs for GCSE Mathematics with 14 exam-style questions and 12 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 1 of 10 in this topic. Use this introduction to connect the idea to the wider topic before moving on to questions and flashcards.
Graphs That Tell Real Stories
Every time you track a journey on a satnav, check a bus timetable, or work out whether a deal is cheaper, you are reading a real-life graph. These graphs do not just show abstract numbers — they show distance travelled, money spent, temperature rising, or water filling a tank. Once you can read what a graph is saying, you can answer almost any contextual question the examiners throw at you.
Practice questions for Real-Life Graphs
On a distance-time graph, what does a horizontal (flat) section represent?
A distance-time graph shows a section with a negative gradient. Explain what a negative gradient means in the context of a distance-time graph.
Quick recall flashcards
Formula for speed from a distance-time graph?
Speed = gradient = (change in distance) / (change in time)
Speed = (y2 - y1) / (x2 - x1)
Units: always check axes — e.g. km/h, m/s, miles/minute
How do you use a conversion graph to convert a value?
1. Find your value on the known axis
2. Draw a line straight up (or across) to the graph
3. Draw a line across (or down) to the other axis
4. Read off the converted value
Always use a ruler for accuracy.
