Week 2 Overview
Week 2
Features of Linear Functions
- Student-Friendly Goal
- To understand how linear functions describe constant change and identify key features, especially intercepts, to tell the story of a relationship.
- Major Skills
- Writing linear expressions and function rules from contexts, interpreting rates of change and starting values, finding and interpreting x- and y-intercepts, and connecting equations, tables, graphs, and contexts.
- NC Math 1 Standards
- NC.M1.A-SSE.1, NC.M1.A-CED.2, NC.M1.A-REI.10, NC.M1.F-IF.4, NC.M1.F-BF.1, NC.M1.F-LE.5.
This week focuses on the mechanics and meaning of linear relationships: writing expressions and function rules, identifying intercepts, and connecting different representations.

What to Look For This Week
Identify the rate of change.
Look for the amount that repeats each hour, day, item, or step.
Use intercepts carefully.
A y-intercept happens when x = 0. An x-intercept happens when y = 0.
Connect representations.
If an equation feels confusing, try a table, graph, or context.
