Graphing Calculators are a valuable tool in learning algebra. I recommend that you have a TI83 or TI84 for this class. If you do not have one (or have just misplaced yours) you may find these links to various online graphing calculators to be helpful.
Online Graphing Calculators
-
Option 1: Desmos - Excellent online calculator - easy to use.
-

-
Option 3: This has excellent tools, but may take some time to learn.
-
Option 4: This graphing calculator resembles the commands on the TI84 graphing calculator.
-
Option 5: This graphing calculator can find intersections, max/mins, and intercepts
Online Linear Regression Tool
- You should use a TI-84 Graphing Calculator to Perform the Linear Regression. If needed, you can use this online regression tool.
