Aim: How can we determine proportionality from an equation, a table or a graph?
Homework: Complete Guided Packet and Examples (click on document link below)
Do Now: Write down one question you have from a topic in this unit.
The class again investigated proportional relationships and saw the connection between tables, graphs, and equations. The big idea for today's class is:
When graphed, proportional relationships are STRAIGHT LINES THROUGH THE ORIGIN (0,0).
We also noticed that the constant of proportionality in proportional relationships turns out to be the unit rate.
We noticed that relationships, such as y = 3x + 5 cannot be proportional. Only relationships in the y = kx form can be proportional.
Announcements: There will be a mini-quiz tomorrow, Friday, November 17, 2017. The quiz will cover topics from the guided packet.
