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 |

(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)

For the first set of points, the rate of change is 1. This means that for every increase of 1 in forearm length, there is also an increase of 1 in foot length. For the second set of points, the rate of change is also 1.
