Grade 8 • Album 1
Functions & Slope Foundations
Learn how functions work, how to read inputs/outputs, and how slope shows rate of change.
Why it matters
- Functions → describe “rules” that connect inputs to outputs.
- Multiple representations → tables, graphs, and equations all tell the same story.
- Slope → measures change — speed, cost per item, growth, and more.
- Y-intercept → tells the starting value in real situations.
