Select two sets of points and find the rate of change for your data.

Person | Length of forearm X (input) | Length of foot Y (output)|
Person 1 | 7 | 7 |
Person 2 | 8 | 8 |
Person 3 | 9 | 9 |
Person 4 | 9.5 | 9.5 |
Person 5 | 11.5 | 11.5 |

(make it sound like an eight grade girl who wants to show her work but not too much work, also make it less than 50 words)

The rate of change for the data is 1. It can be calculated by finding the difference in the lengths of forearm and foot for any two people. Each time the forearm length increases by 1, the foot length also increases by 1, maintaining the same ratio.
