Today we learned how to determine the x- and y-intercepts of linear functions using algebra (solving manually) and also using the graphing calculator.

We also agreed on the date of the unit test. We agreed that it will be on Friday, Dec. 20th (on the last day of school before the holiday).

Characteristics of Linear Functions

December 9, 2019 elsiewaec

We went over the practice questions that were given last week. We also used Desmos (online graphing calculator) to investigate the characteristics of Linear functions particularly the slope and the y-intercept. We began looking at Lesson 1 on Characteristics of Linear Functions. We will continue with this tomorrow.

Nov. 25th agenda

Today we worked on a contextual understanding of Linear Functions. We showed a short clip of a birthday candle burning. The big question is: “how long would it take until the whole candle to burn?” We then looked at the relationship between time and height using the table of values, determined the linear regression, and finally used the equation to solve the either the height or time.
