Big Ideas: Linear functions show a constant rate of change between the variables. This constant rate of change is shown through a straight line when points are connected. If at any point the line does not remain straight then the function is not linear. This lesson is the first in a series of ten which address prior knowledge and introductory skill relating to increasing or decreasing linear functions. This lesson provides students the opportunity to inspect various graphs and determine if they are linear or nonlinear. Students will learn that mathematical relationships can be represented and analyzed using words, tables, graphs, and equations. They will also learn that the graph of a relation can be analyzed to determine if the relation is a function. Vocabulary: coordinate points, x axis, y axis, linear, nonlinear, function, increase, decrease Special Materials: Copies of task for students who need printed notes as designated in 504 plans and/or IEP.
