Solving Systems of Linear Equations: Methods Enhanced via Technology
Why use a technology based method?
How many ways?
Tables (The classical approach) Organized Guess and Check
Tables (With Technology)
Graphing Methods
Graphing via the TI-80/1/2/3s
Graphing Calculator y=-2x+7 & y=x+1
PPT Slide
Using the intersect feature to find an “exact” answer.
CAS (Derive for Windows) “Adding more power and options”
TI-Interactive (Calculator emulator, CAS, Word processor and much much more)
y=3cos(x) & y=x2 -8
Pulling it Together Examining the Tables
