Unit of Instruction  Focus 10: Applications of Functions 

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 nonlinear 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 yintercept in terms of the situation.
