Algebra Applications: Linear Functions

For algebra teachers looking for real-world applications of algebra, this video series is ideal. Each program includes three fully worked-out examples, along with the use of graphing calculators to solve the problems. In particular, TI-Nspire calculator keystrokes are shown for each algebra application. In this program, these three applications are explored: – Cycling in Tuscany is fun, and it's also a great opportunity to study slope. – The Alaska National Wildlife Refuge (ANWR) offers the potential of a lot of oil, but it is a politically controversial area as well. What are the implications for using ANWR oil to reduce America's dependence on foreign oil? Linear regression can help answer the question. – Exercise is a vital part of a healthy lifestyle. In particular, aerobic exercise stresses and strengthens the heart. But as you get older the amount of stress your heart can take changes. This is captured in a linear function.
