Rules and Graphs of Linear Functions

ID del recurso:
This lesson focuses on linear function rules and graphs. Students begin by reviewing the meaning of a function, and that a function can be represented by a table, a graph, a formula, or in words. They then explore the relationship between a function and the coordinates of the points on its graph. They examine the effect of changing the value of a in y = ax, and look at the slope of a road defined as the change in y divided by the change in x. They observe the changes in the graph of y = ax + b as the values of a and b change and see what happens to the y-intercept and the slope. They end by making an observation about parallel lines.
