How can we analyze relationships between two variables?AIM:Announcements: Linear relationships Quiz Tuesday 1/24/17HW: Do Now:A bowling ally charges $5 for shoe rental, and then $6 per game. How can you determine if the relationship between total cost and number of games is linear? Explain. Today class was about connecting graphs, tables, and equations to linear relationships. The common thread is that linear relationships have a CONSTANT RATE OF CHANGE. In a graph, a constant rate of change creates a line. In a table, a constant rate of change causes the numbers to change in the same predictable pattern. In an equation, if there is a number that multiplies by the independent variable to get the dependent variable, again, there is a constant rate of change thus a linear relationship. We look at taxi charges ($6 initial fee and $6 per mile), party planners ($8 per person plus $50 setup fee) and like scenarios. Classwork:Students should be able to extend their knowledge of proportional relationships. Remember, proportional relationships are linear relationships (has a constant rate of change) that happen to ALSO go through the origin. Resources:
