Linear Functions

Evaluating if an equation, graph or visual model represents a linear function. Identifying equations, graphs and visual models that represent linear function. Analyzing the domain and range values and determining the type of the function.

Mapped to CCSS Section# 8.F.A.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. For example, the function A = s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.
