# Q3 W4 Jan 27-31 Pre-Algebra Teacher Stephanie Durrance 8th Grade Math (Pre-Algebra) 8th 4 Focus 9: Applications of Functions
Standard(s) Taught
 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
 • identify a linear function as y = mx + b • identify linear functions as having graphs that are straight lines. • identify functions that are not linear from equations, tables, and graphs. • give examples of relationships that are nonlinear functions. • compare/contrast linear vs. non-linear represented as an equation, table, and graphs.

• calculate the 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.
