So far in our study of linear equations, we have been focusing on situations that are neatly linear, which we can tell looking at a table or graph by identifying a constant rate of change. In the real world, often the data we encounter are not quite as "neat" and perfectly linear. Nonetheless, linear relationships do surround us in our world, even if the patterns are not necessarily as apparent as they may be on a crisp math worksheet.
Today we returned to a concept introduced over a month ago: the graph model. A graph model is a straight line or a curve that shows the general trend in a set of data. In todays classwork and homework, we worked with slightly "messier" data that did not lie in a perfectly straight line. After plotting the data, we were able to draw a line that reflected the general trend of the data and, from that line, create a linear equation.

Quiz 2 on Linear Equations were returned today. Please take the opportunity this weekend to talk with your families about what areas you feel you have grown with linear equations and which areas are still challenging for you. Quizzes should be signed by a parent and brought to class Monday. Please see me tomorrow or Monday if you were absent to receive you quiz.
