Reading Between the Lines: Real-Life Graphs — Maths

Reading Between the Lines: Real-Life Graphs

1 of 4

For grown-ups

Companion summary

Have you ever wondered how your phone shows your battery draining over time? Engineers, doctors, and athletes all use graphs to spot patterns and make smart decisions. A distance-time graph can reveal whether someone is walking, sprinting, or standing completely still. When you finish, try sketching a graph of your own day — time on one axis, energy level on the other.

Warm-Up: What Does the Shape Tell You?

Imagine you left home on your bike, rode fast to a friend's house, stopped there for 20 minutes, then cycled slowly back. If someone drew a graph of your distance from home over time, what shape do you think it would have? Think about: when would the line go up? When would it be flat? When would it come back down? Take 60 seconds to sketch or describe that shape in your head before you read on. This kind of graph — where the axes represent real quantities like distance and time — is called a real-life graph, and reading its shape is just as important as reading its numbers.

What does a flat (horizontal) section of a distance–time graph tell you about what the person is doing at that moment?

How to Interpret a Real-Life Graph

A uses two axes to show how one quantity changes as another quantity changes. The horizontal axis (x-axis) almost always shows time. The vertical axis (y-axis) shows the quantity being measured — distance, temperature, water level, speed, cost, or anything else. **Three things to check first:** 1. Read the axis labels and units. A graph of temperature in °C over hours is very different from one of distance in km over hours. 2. Read the scale carefully. Each grid square might represent 1 unit, 5 units, or 100 units — always check. 3. Look at the overall shape before reading individual values. **Describing the shape — key vocabulary:** • *Increasing* — the line goes upward from left to right. The quantity is getting larger. • *Decreasing* — the line goes downward from left to right. The quantity is getting smaller. • *Constant* — the line is horizontal (flat). The quantity is not changing. • *Steep* — the line rises or falls sharply. Change is happening quickly. • *Gradual* — the line rises or falls gently. Change is happening slowly. **Making s:** An inference is a conclusion you draw from the evidence in the graph. For example, if the line is steep and then becomes gradual, you can infer that something slowed down. **Worked Example:** A bathtub is being filled, then left, then drained. The graph below shows water depth (cm) against time (minutes). • From 0 to 4 minutes: the line rises steeply from 0 cm to 40 cm. → The tap is on and water is filling quickly. • From 4 to 10 minutes: the line is flat at 40 cm. → The tap is off; nobody is in the bath yet or the bath is just sitting full. • From 10 to 14 minutes: the line falls steeply from 40 cm to 0 cm. → The plug has been pulled and the bath is draining quickly. Notice: no numbers were hard to find — you just read across from the y-axis and down to the x-axis at the point you care about. Always use a ruler or the edge of a finger to keep your reading straight.

Worked example

Graph: Water depth (cm) vs Time (minutes) for a bathtub. Data points: (0, 0) → (4, 40) → (10, 40) → (14, 0) Q: What was the water depth at 7 minutes? A: At 7 minutes the graph is in its flat section (between 4 and 10 minutes), so the depth = 40 cm. Q: During which period was the water level changing most rapidly? A: From 0–4 min the depth rose 40 cm in 4 minutes (10 cm per minute). From 10–14 min it fell 40 cm in 4 minutes (10 cm per minute). Both sections have the same steepness, so the rate of change was equal during filling and draining. Q: What was happening between 4 and 10 minutes? A: The line is flat at 40 cm, so the water depth was constant — the tap was off and the plug was in.

Now You Try

Try it yourself

Use the graph description below to answer all five questions. A cyclist sets off from home. The graph shows their distance from home (km) against time (hours). Key points on the graph: (0, 0), (1, 12), (2, 12), (3, 20), (4, 0). Read each question carefully, then choose the best answer.

1. What was the cyclist's distance from home at 2 hours?

2. What was the cyclist doing between 1 hour and 2 hours?

3. Between which two hours did the cyclist travel the greatest distance?

4. What does the section from 3 hours to 4 hours tell us about the cyclist's journey?

5. Between hours 2 and 3, the line rises from 12 km to 20 km. Compared with the section from 0 to 1 hour (0 km to 12 km), how does the steepness compare, and what does this mean for the cyclist's speed?

Bring It Together

Always read the axis labels and scale before anything else — they tell you what the graph is actually measuring.
The shape of the line tells the story: steep = fast change, flat = no change, rising = increasing, falling = decreasing.
An inference links what you see in the graph back to the real-world situation — ask yourself 'what must have been happening at this point?'

1. A graph shows the temperature (°C) in a greenhouse over 6 hours. From 0 to 2 hours the line rises steeply from 15°C to 35°C. From 2 to 5 hours the line is flat at 35°C. From 5 to 6 hours the line falls gradually to 28°C. Which statement correctly interprets the graph?

🌱 Reflect

Think of one graph you have seen outside school — on a news website, in a sports app, or on a food packet. What were the axes? What trend did it show? Could you now describe that trend using the vocabulary from this lesson?
