Don't worry, I can do linear regression and equations solvers on the ti-83. Thanks for all your help Shawn!

Just linear regression with the points:
(0,1),(3,1.4),(6,1.9),(9,2.5),(12,3.3),(15,3.8)
then find what y will be when x = 21.

That was really helpful; i use TI-89 so doing regressions is a pain on that.

Yes, it is way better. If you need any more help feel free to post some of the odd regression problems, take some getting used to.
