Aim: How can we find a unit rate in a description, an equation, a table or a graph?Homework: Accept Khan Invitation. Follow instructions on RKA GmailDo Now: Write a useful unit rate for each situation. 1. You drive 300 miles in 6 hours. 2. A snail went 2 miles in 5 hours. Classwork: 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: ## Leave a Reply. |
