Words we use
| Word | Plain English | What you do |
|---|---|---|
| Flat, or level | The output is not changing: stopped, resting, holding steady. | On a distance graph it means stopped. Check what the axis measures before you say what flat means. |
| Steeper means faster | A steep stretch changes more in each minute than a gentle one. | Compare two climbs or two drops by how steep they are. |
| Climbs | The graph is increasing: the output is growing. | Draw it rising, left to right. Steep if fast, gentle if slow. |
| Drops | The graph is decreasing: the output is shrinking. | Draw it falling, left to right. |
| Jumps | A sudden change all at once: a deposit, a crowd getting on, a price change. | Draw a vertical step. |
| Increasing, decreasing, intercept, maximum, minimum | The Lesson 4 words. Climbing, falling, where it crosses an axis, the highest and lowest points. | Use them to tell the story. |
| Distance graph versus speed graph | Same shape, different story. Flat on a distance graph is stopped; flat on a speed graph is steady motion. | Always read the axis labels first. |
