Name the units.
A rate is clearer when you can say what changes per 1 unit of input.

Week 4 Overview
Week 4
Applications of Linear Functions & Data
- Student-Friendly Goal
- I can use linear models to interpret real-world situations, analyze data patterns, and make reasonable predictions.
- Major Skills
- Interpreting rate of change in context, analyzing scatter plots, using regression models, calculating residuals, and distinguishing association from causation.
- NC Math 1 Standards
- NC.M1.F-IF.1, NC.M1.F-IF.2, NC.M1.F-IF.4, NC.M1.S-ID.6a, NC.M1.S-ID.6b, NC.M1.S-ID.6c, NC.M1.S-ID.8, NC.M1.S-ID.9.
This week focuses on moving from calculation to interpretation. We will use linear models to describe relationships, make predictions, and understand the limits of data.

What to Look For This Week
Check the context.
Use the situation to decide which inputs and outputs make sense.
Look for the trend.
Scatter plots are about the overall pattern, not just one point.
Treat predictions as estimates.
Models can be useful without guaranteeing the exact real-world result.
