Algebra (Class 19)
Announcements
All word problems need to be solved so that I can see “GUESS” from your work.
Overview
In today’s class we continue to work with concepts and skills related to area and perimeter. We see how an equation can be written to represent the various tables of data we have constructed (width v. length, perimeter v. length, area v. length) and develop our understanding of when a function will be linear and when it will not. We also formalize our definition of slope ∆y/∆x) and the y-intercept (the y-value when x=0).
