- Purpose of use
- I was given 3 temperature measurements by a customer where X was known, and Y was given by the customer. Graphed, these measurements appeared to be linear, so this calculator allowed me to quickly compute slope/intercept values to compute the entire (useful) temperature scale from this customer''s 3 measurements.

- Purpose of use
- Do not have a correct graphing calc.
- Comment/Request
- I would suggest making an equation for the linear regression; the single numbers are not very useful by themselves. Also, an r^2 value would be good as well.
