Modeling Word Problems with Linear Functions Part 1

Identify Independent and Dependent variables at 2:22 Building a table of values to help develop the formula at 6:55 Graphing the Linear Function at 11:17 (If domain is restricted to Whole numbers the graph is just the disconnected points.) How do we know a Linear Model is a good choice at 15:45 Applying the Linear Function to answer specific questions at 20:32 (Solving a two step equation and two step inequality) Interpreting the slope, y-intercept, and x-intercept at 27:04 Use of TI-NSPIRE to find the intersection of 2 graphs at 31:54 Check out http://www.ProfRobBob.com/, there you will find my lessons organized by class/subject and then by topics within each class.
