A constructed feeder model delivers cord from a zero-length start at 1.5 meters each minute, for 0 to 3 minutes. Let x mean time in minutes and y mean total cord length in meters.
| x: time (minutes) | y: cord length (meters) |
|---|---|
| 0 | 0 |
| 1 | 1.5 |
| 2 | 3 |
| 3 | 4.5 |
Point (2, 3) means 2 minutes and 3 meters, in that order. The quotient y ÷ x answers meters for each minute; x ÷ y answers a different question. Keep the units beside the numbers.
- Write or say what the point (3, 4.5) means.
- Find the requested meters per minute from two positive-time pairs. State the constant and a rule for y.
- Explain what (0, 0) and the point at one minute mean in this model. Describe the graph’s relation to the origin.

An oral, written or labeled-table response may show the reasoning. If someone supplies the constant, rule or classification, record that help.
