Standard(s) Taught

MAFS.8.EE.2.5

Graph proportional relationships, interpreting the unit rate as the slope of the graph.  Compare two different proportional relationships represented in different ways.

MAFS.8.F.1.3

Interpret the equation y=mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear.

MAFS.8.F.2.4

Construct a function to model a linear relationship between two quantities.  Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph.  Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.

Learning Targets and Learning Criteria

Students are successful when they can…

• use a graph, a table, equation, or verbal description to determine the unit rate of a proportional relationship.
• graph a proportional relationship in the coordinate plane.
• use the unit rate to make comparisons between various proportional relationships represented in different ways (graphs, tables, equations, and verbal description).
• identify a linear function as y=mx + b;
• identify linear functions as having graphs that are straigt lines.
• identify functions that are not linear from equations, tables, and graphs.
• give examples of relationships that are non-linear functions.
• calculate slope/ rate of change from a table, graph, equation or two points.
• write a linear function rule for a given relationship.
• describe the slope and y-intercept in terms of the situation.
