Students should use their knowledge of proportional and non-proportional relationships to determine when functions are proportional or non-proportional. Proportional functions will be in the form y = kx and non-proportional functions will be in the form y = mx + b. Students should be determining if a function is proportional or non-proportional in a mathematical or real-world situation.
8.5 Proportionality. The student applies mathematical process standards to use proportional and non-proportional relationships to develop foundational concepts of functions. The student is expected to:
(H) identify examples of proportional and non-proportional functions that arise from mathematical and real-world problems
